Answer 1

$\huge \mathcal{ \fcolorbox{cyan}{black}{ \green{Solution:-}}}$

molar mass of ch4 = 16.04 g/mol

molar mass of p4 = 123.895048 g/mol

Answer 2

Explanation:

➜ㅤTo calculate the molar mass add the mass of each element

➜ㅤThe molecular formula of methane is CH4. There are total 4 bonds between C and H atom

Molar mass of ch4

• 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

Molar mass of P4

• Molar mass of phosphors = 4 × Molar mass of P
• 4 × 31 = 124g
