1.5 mol of $O_{2}$ combine with Mg (Magnesium) to form oxide MgO . The mass of Mg (at. weight $= 24$ ) that has combined is :-

Options:

Answer:

Solution:

$Mg + \frac{1}{2} O_{2} \to MgO$

$1 m o l e M g \leftarrow 0.5 m o l O_{2} \frac{1.5}{0.5} = 3 m o l \leftarrow 1.5 m o l O_{2} M o l eo f M g = 3 m o l M a sso f M g = 3 \times 24 = 72 g$
