$n=4.1mol$

Explanation:

Hello,

In this case, we can use the ideal gas equation:

$PV=nRT$

So we know the temperature, pressure and volume, therefore we can easily compute the required moles as shown below:

$n=\frac{PV}{RT}=\frac{2.0atm*101L}{0.082\frac{atm*L}{mol*K}*600K} \\\\n=4.1mol$

Best regards.

The molar heat of vaporization of water is 40.7 kJ mol . How much heat must be absorbed to convert 50.0 grams of liquid water at

podryga [215]

Molar mass of water 18g/mol

Number of mols = 50.0g/18g/mol =2.78 mol
