Answer
P H2 = 4.56 atm
P N2 = 2.28 atm
P total = 6.85 atm
Work Step by Step
the gas law : PV =nRT
the gas law : Ptotal = (nH2+ nN2) RT / V
P: is gas pressure ??
V: gas volume (10.0 dm3 = 10.0 L)
R: gas constant (0.0821 L-atm / mole-K)
T: gas temperature in Kelvin (278.15
PH2 = 4.56 atm
PN2 = 2.28 atm
Ptotal = (nH2+ nN2) RT / V
= (2+1) × 0.0821 × 278.15 / 10
= 6.85 atm
