Question

the mass of 2.8 litres of co2

Answer 1

Hi,

Your answer is here

Gram molecular mass of CO2 = 12 + 32 = 44 g
This implies that the mass of 22.4 lit of CO2 is 44 g
Therefore
Mass of 1 lit of CO2 = 44/22.4 g
Mass of 2.8 lit of CO2 = 44/22.4 * 2.8
                                      = 5.5 g

The mass of 2.8 lit of CO2 is 5.5 g.
