37.6% CH4 62.4% C3H8 mixture 424 g gram CO2

37.6% CH4와 62.4% C3H8인 혼합물 424 g을 연소시키면

몇 그램의 CO2가 생성될까?

How many grams of CO2 are produced

by the combustion of 424 g of a mixture

that is 37.6% CH4 and 62.4% C3H8 by mass?

---------------------------------------------------

424 g × (37.6/100) = 159.4 g CH4

CH4 연소 반응식

CH4 + 2O2 → CO2 + 2H2O

( 참고 https://ywpop.tistory.com/7441 )

질량비로 계산하면,

CH4 : CO2 = 16.04 : 44.01 = 159.4 g : ? g

? = 44.01 × 159.4 / 16.04 = 437.4 g CO2

424 g × (62.4/100) = 264.6 g C3H8

C3H8 연소 반응식

C3H8 + 5O2 → 3CO2 + 4H2O

질량비로 계산하면,

C3H8 : 3CO2 = 44.10 : 3(44.01) = 264.6 g : ? g

? = 3(44.01) × 264.6 / 44.10 = 792.2 CO2

437.4 + 792.2 = 1229.6 g CO2

답: 1230 g
