Some Basic Concepts Of Chemistry Question 306

Question: Number of gm of oxygen in 32.2 g $N a_{2} S O_{4} .10 H_{2} O$ is [Haryana PMT 2000]

Options:

A) 20.8

B) 22.4

C) 2.24

D) 2.08

Show Answer

Answer:

Correct Answer: B

Solution:

$N a_{2} S O_{4} . 10 H_{2} O$ $= 2 \times 23 + 32 + 4 \times 16 + 10 \times 18$

$= 46 + 32 + 64 + 180 = 322 g m$

322gm $N a_{2} S O_{4} .10 H_{2} O$ contains = 224 gm oxygen 32.2gm $N a_{2} S O_{4} .10 H_{2} O$ contains = $\frac{32.2 \times 224}{322} = 22.4, g m$
