The density of carbon dioxide is equal to 1.965 kg `m^(-3)` at 273 K and 1 atm pressure. Calculate the molar mass of `CO_(2)`.

Explanation

Molecular mass== Density `xx` Molar volume
Molar volume of `CO_(2)=2.24xx10^(-2)m^(3)`
Density of `CO_(2)=1.965kgm^(-3)`
`:.` Molecular mass of `CO_(2)=1.965xx10^(3)g m^(cancel(-3))xx2.24xx10^(-2)cancel(m^(3)`
`1.965xx10^(1)xx2.24`
