How many moles of hydrogen gas are present in a 50.0 L steel container if the pressure is at 10.0 ATM and the temperature is 27.0 C(R=.0821atm/mole-k)

Respuesta :

• We are given the following :

P = 10 Atm

V= 50 L

R=0.0821atm/mole-k)

T= 27°C = 273.15 + 27°C = 300 .15 K = 300K

• We will use the following formula in order to find moles of hydrogen gas

PV = nRT

n = PV /RT

=( 10 * 50 )/ ( 0.0821 * 300)

n = 500/24.63

n = 20.3 moles

Therefore ; moles of hydrogen gas present = 20.3 moles
