###### FREE Expert Solution

We’re being asked to calculate the temperature of hydrogen in °C.

We will use ideal gas equation to calculate for the pressure:

$\overline{){\mathbf{PV}}{\mathbf{=}}{\mathbf{nRT}}}$

P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K
