Carbon forms CO and CO2. For 12 g of carbon, the oxygen masses are 16 g and 32 g. Which law does this show?
ADefinite proportions
BMultiple proportions
CConservation of mass
DGaseous volumes
Answer & Solution
Correct answer: B. Multiple proportions
Different oxygen masses combining with a fixed carbon mass are in the simple ratio 1 : 2, which is the law of multiple proportions.
