Question

What mass of carbon dioxide gas is present for a `52.0*mL` volume, at a temperature of `303*K`, and a pressure of `0.907*atm`?

Answer 1

`"Mass of carbon dioxide"~=80*mg`

Explanation:

From the Ideal Gas equation....

`n=(PV)/(RT)=(0.907*atmxx52.0*mLxx10^-3*L*mL^-1)/(0.0821*(L*atm)/(K*mol)xx303*K)`

`=1.90xx10^-3*mol`

And thus the mass of gas is given by.............

`"molar quantity"xx"molar mass"=1.90xx10^-3*molxx44.01*g*mol^-1=??g`
