a sample mixture of ch4 and c2h6 weighing 0.732 g burned to give 2.064 g co2. What is the mass of ch4 in the mixture?

    Don't get sloppy in chemistry with no caps.
    Let x = mass CH4
    and y = mass C2H6 and set up two equations and solve simultaneously.
    -----------------------------------
    x+y=0.732
    (x*44/16) + (2y*44/30) = 2.065
    Post your work if you get stuck.
