1.09 g of hydrogen contained in a 2.00l container at 20.0 °c what is the pressure in the container

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
