Số mol hỗn hợp khí X: n(X) = n(N2) + n(CO2) = 5,6/22,4 = 0,25mol
n[Ca(OH)2] = 5.0,02 = 0,1mol
n(CaCO3) = 5/100 = 0,05mol
Ca(OH)2 + CO2 → CaCO3 + H2O
0,05______0,05____0,05
Ca(OH)2 + 2CO2 → Ca(HCO3)2
0,05_______0,1_______0,05
Số mol mỗi khí trong X
n(CO2) = 0,05+0,1=0,15mol
n(N2) = 0,25-0,15 = 0,1mol
Khối lượng hỗn hợp X: m(X) = m(N2) + m(CO2) = 28.0,1 + 44.0,15 = 9,4g
→ M(X) = 9,4/0,25 = 37,6 → Tỉ khối d(X/H2) = 37,6/2 = 18,8
