To calculate the number of moles present in a sample of CH4, you need to divide the mass of the sample by the molar mass of CH4.
Number of moles = Mass / Molar mass
Number of moles = 10.55 g / 16.05 g/mol
Number of moles = 0.657 moles
Therefore, the answer is:
a) 0.657 moles of CH4
Number of moles = Mass / Molar mass
Number of moles = 10.55 g / 16.05 g/mol
Number of moles = 0.657 moles
Therefore, the answer is:
a) 0.657 moles of CH4
