Question

Calculate the volume of 3.2g of carbon dioxide molecule
​

Answer 1

Answer:

1792cm3 (0.0017m3)

Explanation:

1 mole of CO2 at STP occupies, 22.4liter (0.0224m3) of gas.

molecular weight of CO2 is 44g/mol

means, 40g in 1 mole

so,

3.2g is how much mole?

= 3.2/40

= 0.08 mol

now, we know that, 1 mole of CO2 occupies 0.0224m3

0.08 mole occupies how much?

Volume of 3.2g CO2 = (0.08 x 0.0224)/1

Volume of 3.2g of CO2 = 0.001792m3

i.e. 1792cm3
