In the following reaction sequence, the major product P is formed.

$$\ce{H-C#C-(CH2)15-CO2Et ->[\text{i) } Hg^{2+}, H3O+][\text{ii) Zn-Hg/HCl; iii) } H3O+, \Delta] P}$$

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 $\ce{CaCl2}$ yields Ca-soap R, quantitatively. Starting with one mole of Q, the amount of R produced in gram is _____.

[Given, atomic weight: H = 1, C = 12, N = 14, O = 16, Na = 23, Cl = 35, Ca = 40]

In the given reaction scheme, P is a phenyl alkyl ether, Q is an aromatic compound; R and S are the major products.

$$\mathbf{P} \xrightarrow{\ce{HI}} \mathbf{Q} \xrightarrow[\text{(iii) } \ce{H3O+}]{\text{(i) NaOH; (ii) } \ce{CO2}} \mathbf{R} \xrightarrow[\text{(ii) } \ce{H3O+}]{\text{(i) } \ce{(CH3CO)2O}} \mathbf{S}$$

The correct statement about S is
