A hydrocarbon mixture known to contain methane, ethene and butane only has a volume of 6.00L, a pressure of 2 bar and density of 2.404x103 g/mL at 25°C. When this mixture reacted with hydrogen gas in the presence of platinum metal, 0.3145 g of hydrogen gas was consumed. When the same amount of the mixture was completely combusted, 43.13g of carbon dioxide and 23.69g of water were produced. What was the mass percentage of methane in the mixture? (assume all reactions went to completion). 45% 19% 30% 50% 24%
