Answer:

n=11.1mol

Step-by-step explanation:

Hello,

In this case, we use the ideal gas equation which allows us to understand the pressure-volume-mole-temperature behavior of hydrogen gas:

PV=nRT

Thus, solving for the moles, we obtain:

n=(PV)/(RT)

We cannot forget that the temperature should be used in absolute units (Kelvins), therefore, the resulting moles turn out:

$n=(0.96atm*250L)/(0.082(atm*L)/(mol*K)*(-10.0+273.15)K) \\\\n=11.1mol$

Best regards.
