A) \[72g\]
B) \[36g\]
C) \[48g\]
D) \[24g\]
Correct Answer: A
Solution :
\[2Mg+{{O}_{2}}\xrightarrow{{}}2MgO\] \[\because \] 1 mole of oxygen is combined with 2 mole of \[Mg\] to produce \[MgO\] Hence \[2\times mol\] wt. of \[Mg\] \[=2\times 24=48\] \[\therefore \] 1.5 mole of oxygen combines with \[=1.5\times 40=6gm\].You need to login to perform this action.
