    Answer: 0.0195g of CO2 is produced

    Explanation:

    CH4 + 2O2 - > CO2 + 2H2O

    Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol

    Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol

    From the equation,

    16g of CH4 produce 44g of CO2.

    Therefore 7.10*10^-3 of CH4 will produce Xg of CO2 i. e

    Xg of CO2 = (7.10*10^-3x44) / 16 = 0.0195g
