Academics

Methane, CH4, the major component of natural gas burns in air to form CO2 and H2O. What mass of water is formed in the complete combustion of 5.00 ´ 103 g of CH4?

5.00 ´ 103 g
1.00 ´ 104 g
5.65 ´ 103 g
1.12 ´ 104 g
none of these

5.00' 10^3 assuming unlimited O2 & complete burn

5 CH4 + 10 O2 --> 5 O2 + 10 H2O

1 H2O = 18 g

18g x 10 = 180g x 2 = 360g
