Question

Calculate the mass of 22.4 litres of CO2

Answer 1

Answer:

Gram molar mass of 22.4 litres of CO2 at STP = 44grams.

Answer 2

Answer:

12 g

Explanation:

We know that,

$\underline{\boxed{ \sf Moles = \dfrac{Volume\:(in\: litre)}{22.4}}}$

$\sf Moles \: of \: CO_2= \dfrac{22.4}{22.4} = 1\: mole$

$\sf Mass \: of \: CO_2= 1× 12 \: g = 12 \: g$

Hence the mass of CO2 in 22.4 litres is 12 grams.
