Question

2.2g of co2 at NTP occupy a) 2.24L b) 11.2L c) 22.4L d) 1.12L

Answer 1

Answer:(d).

Explanation: So basically you have to relate the number of moles to the volume.

So number of moles of CO2= 2.2g/44

(Because 44 is the molecular mass)

=1/20 moles.

We know at NTP, one mole of any substance occupies a volume of 22.4 L, so

1/20mol will occupy how much?

=22.4*(1/20)=1.12 L.

Answer 2

Answer:

(d) 1.12 L

Explanation:

Molar Mass of CO2 = 44 g

44 g = 1 mole

44 g => 22.4 L

2.2 b => x L

44x = 22.4*2.2

x = 1.12 L

(d) 1.12 L
