각 기체의 몰수를 계산하면,
2.0 g / (28 g/mol) = 0.071429 mol N2
( 참고 https://ywpop.tistory.com/7738 )
0.40 / 2 = 0.2 mol H2
9.0 / 32 = 0.28125 mol O2
전체 몰수를 계산하면,
0.071429 + 0.2 + 0.28125 = 0.552679 mol
PV = nRT
( 참고 https://ywpop.tistory.com/3097 )
P_tot = n_tot RT / V
= [(0.552679) (0.08206) (273.15+27)] / (2.00)
= 6.81 atm
[Q] 2.8 g of N2, 0.40 g of H2 and 6.4 g of O2
placed in a container of 1.0 L capacity at 27℃.
The total pressure in the container is
[Q] 12 g N2, 4 g H2 and 9 g O2
are put into a one litre container at 27℃.
What is the total pressure?
