Question

$ \mathrm{A}+2 \mathrm{~B} \longrightarrow \mathrm{AB}_2 $
36. 0 g of 'A' (Molar mass : $60 \mathrm{~g} \mathrm{~mol}^{-1}$ ) and 56.0 g of 'B' (Molar mass : $80 \mathrm{~g} \mathrm{~mol}^{-1}$ ) are allowed to react. Which of the following statements are correct ? 
A. ' A ' is the limiting reagent. 
B. $ 77.0 \mathrm{~g}$ of $\mathrm{AB}_2$ is formed. 
C. Molar mass of $A B_2$ is $140 \mathrm{~g} \mathrm{~mol}^{-1}$. 
D. $15.0 \mathrm{~g}$ of A is left unreacted after the completion of reaction.
