What volume of $C O_{2}$ released at STP on heating $9.85$ $g$ of $B a C O_{3}$ ? (Atomic mass of $B a = 137$ ), (assuming fully decomposed)

Options:

Answer:

Solution:

$B a C O_{3} \to B a O + C O_{2} ↑$
Molecular weight of $B a C O_{3} = 137 + 12 + 3 \times 16 = 197$
$∵ 197 g$ produces $22.4 L$ at S.T.P.
$∴ 9 .85 g$ produces $\frac{22.4}{197} \times 9.85 = 1.12$ $L$ at $S . T . P .$
