Answer:
6.55 atm
Explanation:
we can use the ideal gas law equation to find the pressure of the container
PV = nRT
where P - pressure
V - volume
n - number of H₂ moles - 1.09 g / 2 g/mol = 0.545 mol
R - universal gas constant - 0.08206 L.atm/mol.K
T - temperature in kelvin - 20 °C + 273 = 293 K
substituting the values in the equation
P x 2.00 L = 0.545 mol x 0.08206 L.atm/mol.K x 293 K
P = 6.55 atm
pressure in the container is 6.55 atm
