Answer:

$m=13.1gO_2$

Explanation:

Hello,

In this case, by using the ideal gas equation, we first compute the moles of oxygen at the given volume, pressure and temperature:

$PV=nRT\\\\n=\frac{PV}{RT}=\frac{2.0atm*5L}{0.082\frac{atm*L}{mol*K}(25+273.15)K} =0.41mol$

Then, since molar mass of gaseous oxygen is 32 g/mol, we compute the contained mass in grams as shown below:

$m=0.41mol*\frac{32g}{1mol}\\\\m=13.1gO_2$

Best regards.
