claculate 50g of CH4

To calculate the mass of 50g of CH4 (methane), we need to know the molar mass of CH4.

The molar mass of CH4 can be determined by adding up the atomic masses of its constituent atoms. The atomic mass of carbon (C) is approximately 12.01 grams per mole (g/mol) and the atomic mass of hydrogen (H) is approximately 1.008 g/mol.

Since methane (CH4) contains one carbon atom and four hydrogen atoms, we can calculate its molar mass as follows:

Molar mass of CH4 = (1 x molar mass of carbon) + (4 x molar mass of hydrogen)
= (1 x 12.01 g/mol) + (4 x 1.008 g/mol)
= 12.01 g/mol + 4.032 g/mol
= 16.042 g/mol

Now that we know the molar mass of CH4 is 16.042 g/mol, we can calculate the number of moles in 50g of CH4 using the formula:

Number of moles = Mass (in grams) / Molar mass

Number of moles = 50g / 16.042 g/mol
≈ 3.1157 moles (rounded to four decimal places)

Therefore, 50g of CH4 is approximately equal to 3.1157 moles.
