How many moles are in 564 grams of copper

Answers

Answer:The answer is 63.546.

Explanation: The answer is 63.546. We assume you are converting between grams Copper and mole. You can view more details on each measurement unit: molecular weight of Copper or mol. The molecular formula for Copper is Cu. The SI base unit for amount of substance is the mole. 1 grams Copper is equal to 0.015736631731344 mole

Answer:

5.64 of copper

Explanation:

Given: 564 grams of copper

To find: in copper

Solution: If 1 grams Copper = 0.01 mole,

Then, 564 grams = multiply 564 and 0.01 mole

564 × 0.01 = 5.64

Therefore, there are 5.64 of copper in 564 grams

pls help and show work!!!

Answers

Answer:

44.9g

Explanation:

You have to convert grams of CH4 to moles, use the mole-to-mole ratio of CH4 to water, and convert back to grams.

(20.0g CH4)(1 mol CH4/16.04g)(2 mol H2O/1 mol CH4)(18.01 g H2O/ 1 mol) = 44.9127 g

An electric car has a mass of 2,000 kg. the engine is producing a force of 3,500 N to move the vehicle forward,but it must overcome air friction equal to 500 N
What is the acceleration of the electric car m/s2?
record your answer and fill in below

Answers

Answer:

1.5 m/s²

Explanation:

From the diagram,

F-F' = ma............... Equation 1

Where F = Forward force of the vehicle, F' = Frictional force, m = mass of the electric car, a = acceleration of the car.

make a the subject of the equation

a = (F-F')/m........... Equation2

Given: F = 3500 N, F' = 500 N, m = 2000 kg

Substitute into equation 2

a = (3500-500)/2000

a = 3000/2000

a = 1.5 m/s²

How many grams of NaOH are produced from 2.1g of Na2O?
Na2O + H20 --> 2NaOH

Answers

Answer:

2.72g

Explanation:

The balanced equation of this reaction is given as follows:

Na2O + H20 --> 2NaOH

Based on this balanced equation, 1 mole of Na2O will produce 2 moles of NaOH.

First, we need to convert mass of Na2O into moles by using the formula;

mole = mass/molar mass

Molar mass of Na2O = 23(2) + 16

= 46 + 16

= 62g/mol

mole = 2.1g/62g/mol

mole of Na2O = 0.034mol

Hence, if 1 mole of Na2O will produce 2 moles of NaOH.

Then, 0.034mol of Na2O will produce (0.034 × 2) = 0.068mol of NaOH.

To convert mole of NaOH to mass, we use;

mole = mass/molar mass

Molar mass of NaOH = 23 + 16 + 1 = 40g/mol

0.068 = mass/40

mass of NaOH produced = 2.72g.

A pool float was filled with air to capacity in the middle of a hot day. The next morning the pool float looked different yet no gas escaped or entered the float. Describe what you think the float looked like in the morning and why it occurred.

Answers

Answer:

The pool float looked would have looked deflated the next morning.

Explanation:

When temperature decreases the volume decreases

Answer:

The pool float most likely looked a little deflated or pushed in

Explanation:

The pool float most likely looked a little deflated or pushed in. This is because during the night temperatures most likely dropped. These cold temperatures during the night would have caused the air molecules inside the pool float to come closer together which would cause there to be more excess space inside the pool float. Therefore, allowing it to collapse into itself. This would be far worse if the float was filled with helium or another gas other than O2.

Now that you have exercised, walked your

or nap. Melatonin has the chemical formula
C13H16N2O2. The amount in your body at any
time is very small - less than 10 milligrams
(0.01 g)! Convert the melatonin to moles so
you can rest

Answers

Answer: The moles of melatonin are 0.000043

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

Given mass of melatonin = 0.01 g

Molar mass of melatonin [tex](C_{13}H_{16}N_2O_2)[/tex] = 232.28 g/mol

[tex]\text{Number of moles of melatonin}=\frac{0.01 g}{232.28g/mol}=0.000043mol[/tex]

Thus the moles of melatonin in 0.01 g are 0.000043

You heat 100 mL of water and 1000 mL of water using 40,000 joules of energy. What would be the outcome of this experiment? *
A. The 100 mL of water would be a higher temperature than the 1,000 mL of water.
B. The 100 mL of water would be a lower temperature than the 1,000 mL of water.
C. They would both be the same temperature.
D. There is not enough information

Answers

Answer:

A. The 100 mL of water would be a higher temperature than the 1,000 mL of water.

Explanation:

Since the volume of water affects temperature, when the volume increases this results in a lower temperature. This means that the water with the smaller volume will have a higher temperature.

Volume of 6.5 moles of Helium at STP is 145.6954 L

Explanation:

As we know

[tex]pV = nRT[/tex]

At STP, temperature is 273.15 K and pressure is 1 atm

n is the number of moles which is equal to 6.5

R is the gas constant = 0.08206 L atm/K mol

Substituting the given values in above equation, we get -

[tex]1 * V = 6.5 * 0.08206 * 273.15\\V = 145.6954[/tex]Liters

Volume of 6.5 moles of Helium at STP is 145.6954 L

Calculate the molar mass of HCI.
