Question

Pls help me in this question (10) chemistry

Answer 1

Explanation:

Given -

• 13.2 g of CO2

To Find -

• Volume occupied by CO2 at STP

Now,

Molar mass of CO2 is :-

→ 12 + 16×2

→ 12 + 32

→ 44 g/mol

Now,

As we know that :-

• Mole = mass/GMM

→ Mole = 13.2/44

⟹ Mole = 0.3

Now,

As we know that :-

• Volume = Mole × 22.4 (in L)

→ Volume = 0.3 × 22.4

⟹ Volume = 6.72 L

Hence,

The volume occupied by 13.2 g of CO2 at STP is 6.72 L

Therefore,

Option 2 is correct.
