To calculate the number of moles of CH4 present in 6.07 g, we need to use the molar mass of CH4. The molar mass of CH4 is 16.04 g/mol.

So, the number of moles of CH4 in 6.07 g can be calculated as follows:

Moles of CH4 = Mass of CH4 / Molar Mass of CH4

Moles of CH4 = 6.07 g / 16.04 g/mol

Moles of CH4 = 0.378 mol

Therefore, there are 0.378 moles of CH4 present in 6.07 g of CH4.
