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 \( \text{NaOH} \) followed by the treatment with \( \text{CaCl}_{2} \) yields Ca-soap R, quantitatively. Starting with one mole of Q, the amount of R produced in gram is ______.
[Given, atomic weight: \( \text{H} = 1 \), \( \text{C} = 12 \), \( \text{N} = 14 \), \( \text{O} = 16 \), \( \text{Na} = 23 \), \( \text{Cl} = 35 \), \( \text{Ca} = 40 \)]
