Identify the major product of the reaction when the given compound is hydrolyzed and heated strongly.

In the following reaction sequence,the major product $P$ is formed. Glycerol reacts completely with excess $P$ in the presence of an acid catalyst to form $Q$. Reaction of $Q$ with excess $NaOH$ followed by the treatment with $CaCl_2$ yields $Ca$-soap $R$,quantitatively. Starting with one mole of $Q$,the amount of $R$ produced in gram is. . . .
