Question

8. Calculate the molecular mass of methane​

Answer 1

Answer:

16.04 g/mol

Formula: CH₄

Melting point: -182 °C

Density: 0.657 kg/m³

Answer 2

Answer:

To calculate the molar mass add the mass of each element The molecular formula of methane is CH4. There are total 4 bonds between C and H atom

Atomic mass of carbon- 12amu Atomic mass of hydrogen- 1amu. Add carbon mass with H mass = 12 + 1 x 4 ) g/mol ( as 4 atoms of H ) 12+4 = 16 g/mol
