    Atomic mass of Carbon= 12.01
    Atomic mass of Hydrogen= 1.008
    Atomic mass of Oxygen= 16
    Therefore, Molar mass of dimethyl ether = 46.07g
    (as 2 x (12.01+ 3 x 1.008) + 16 = 46.07)

    CH3 -O- CH3 (g) + 3O2 ...

    Solution Summary

    Calculates volume of Oxygen consumed in the combustion of gaseous dimethyl ether.
