A sample of natural gas is 85.2% methane, CH4, and 14.8% ethane, C2H6, by mass. What is the density of this mixture at 18°C and 771 mmHg?

 

A sample of natural gas is 85.2% methane, , and 14.8% ethane, , by mass. What is the density of this mixture at 18C and 771 mmHg?

A 5.00 g mixture of methane (CH4) and ethane (C2H6) is combusted in oxygen gas to produce carbon dioxide and water. If 14.09 g of CO2 is produced, how many grams of methane was in the original 5.00 g mixture ?

A 12-gram mixture of methane, CH4, and ethane, C2H6, is completelycombusted in oxygen. If the total mass of H2O produced is 23.4grams, what was the approximate mass of the methane in the originalmixture?

A. 4 g CH4
B. 8 g CH4
C. 5 g CH4
D. 6 g CH4
