Solution

The correct option is D $19.6 g, 63 g$
Atomic weight of $P = 31 g$

Atomic weight of $H_{3} P O_{4} = 98 g$

We know that $31 g$ of $P$ will give 98 g of $H_{3} P O_{4}$ .

Therefore, $6.2 g$ of $P$ will give:= $\frac{98}{31} \times 6.2 = 19.6 g o f H_{3} P O_{4}$ .

Atomic weight of $P = 31 g$

Atomic weight of $5$ moles of $H N O_{3} = 315 g$ .

We know that $31 g$ of $P$ will give 315 g of $H N O_{3}$ .

Therefore, $6.2 g$ of $P$ will give: $\frac{315}{31} \times 6.2 = 63 g$ of $H N O_{3}$ .

Hence, option C is correct.
