The formula for methane is CH4. Four moles of methane would have a mass of how many grams?

Answer 1

To calculate the mass of four moles of methane (CH4), we first need to determine the molar mass of methane. The molar mass of CH4 is the sum of the atomic masses of carbon (12.01 g/mol) and hydrogen (1.008 g/mol) multiplied by the number of atoms in the compound. Therefore, the molar mass of CH4 is 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol. To find the mass of four moles of methane, we multiply the molar mass by the number of moles: 16.04 g/mol x 4 mol = 64.16 grams. Therefore, four moles of methane would have a mass of 64.16 grams.

Answer 2

Taking carbon @ 12.01 g/mol & hydrogen @ 1.01 g/ mol methane has 1 carbon & 4 hydrogen, so it is:

• 12.01g + 4(1.01g) = 16.05g per mole.
• For 4 moles: 4 x 16.05 g = 64.20 g

Answer 3

No. of moles = Given mass of element or compound/ molar mass of element or compound.

Molar mass of Methane(CH4) = 16 g

No. of moles of Methane in 345g = 345/16=21.562 moles.

Answer 4

The molar mass of methane (CH4) is 16.04 g/mol. Therefore, four moles of methane would have a mass of 16.04 g/mol x 4 mol = 64.16 grams.

Answer 5

it's around 67.974g, depending on how acurate the molar mass is (mine is to three decimal places)

Answer 6

1 mole C= 12.01 g

4 moles H= 4.04 g

Therefore, 1 mole of CH4 = 12.01g + 4.04g = 16.05g

Answer 7

molar mass of methane is 16g/mol

so 4 mols is 64 grams

Answer 8

The mass of four moles of methane is about 64g (grams).

Answer 9

Four moles of methane would have a mass of 64,12 grams.

Answer 10

First divide 4 by 16.So answer is 0.25
