Zawartość metanu w gazie ziemnym
40 m3 * 90% = 36 m3
d = m/V => m = V*d d = 0,422 g/dm3 = 422 g/m3
m(CH4) = 36 m3 * 422 g/m3 = 15192 g
n = m/M
M(CH4)=12+4*1 = 16 g/mol
n(CH4) = 15192 g/ 16 g/mol = 949,5 mol
----------------------------------
CH4 + 2O2 ---> CO2 + 2H2O
-----------------------------------
Z jednego mola metanu powstaje 1 mol CO2
n(CO2) = n(CH4) = 949,5 mol
M(CO2) = 12+2*16 = 44 g/mol
m(CO2) = 949,5 mol * 44 g/mol = 41778 g
d = m/V => V = m/d d = 1,297 g/dm3 = 1297 g/m3
V = 41778 g / 1297 g/m3 = 32,2 m3
W wyniku spalania 40 m3 gazu ziemnego powstaje 32,2 m3 CO2
