Question

$1$ mole of a compound contains $1$ mole of $C$ and $2$ moles of $O$. The molecular weight of the compound is :

• A. 3
• B. 12
• C. 32
• D. 44

Answer 1

The correct option is D 44

Given that :

1 mole of compound contains 1 mole of $C$ and 2 moles of $O$.

Therefore, the molecular formula of the compound is $C_1{O}_2$.

$\Rightarrow$ Molecular Formula of the compound $=C{O}_2$

Molecular weight of the compound = $1\times 12$(Molecular weight of the carbon) $+2\times 16$ (Molecular weight )of the oxygen)

$=12+32=44$

Molecular weight of the compound $=44g$

$\therefore$ Molecular weight of 1 mole of the compound $=44g$

Hence the correct option is D.
