Step-by-step explanation:
According to ideal gas equation, product of pressure and volume equals n times R times T.
Mathematically, PV = nRT
where P = pressure
V = volume
n = number of moles
R = gas constant
T = temperature
Since, it is given that no. of moles is 4.53 mol, pressure is 1.78 atm and temperature is 301 K. Value of R will be 0.082
Therefore, calculate the volume as follows.
PV = nRT

V =

= 62.81 L
Thus, we can conclude that volume of hydrogen will be 62.81 L.
