Question

If the molecular mass of a molecule is 52 amu then what will be its molar mass?

• A. 52 g/mol
• B. 62 g/mol
• C. 72 g/mol
• D. 349.5 g/mol

Answer 1

The correct option is A 52 g/mol

Given: Mass of 1 molecule of the compound = 52 amu
$=52\times 1.66054\times {10}^{-24}$ g

Therefore, the molar mass of the given molecule
$=52\times 1.66054\times {10}^{-24}\times 6.022\times {10}^{23}=52g/mol$
