Question

A particular natural gas consists, in mol percents, of 83.0%CH4, 11.2% C2H6, and 5.8%C3H8. A 385-L sample of this gas, measured at22.6 oC and 739 mmHg, is burned at constant pressure inan excess of oxygen gas. How much heat, in KJ's, is evolved in thecombustion reaction? Just do not understand this question in general. Do not knowhow to do the full problem. A particular natural gas consists, in mol percents, of 83.0%CH4, 11.2% C2H6, and 5.8%C3H8.

Explanation / Answer

Volume, V = 385 L

T = 22.6 C = 295.6 K

P = 739 mm Hg = 0.9723 atm
