What mass of carbon dioxide is produced from the complete combustion of 7.10×10−3 gg of methane? Express your answer with the appropriate units.

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

the answer would be a
