Question

A student heats 4.00 g of a blue compound, which reacts completely to produce 2.56 g of a white compound and an unknown amount of colorless gas. What is the mass of this gas?

Assuming that the blue compound was decomposing (e.g., a pyrolysis reaction) and was not reacting with another compound, the 1.44 g of mass loss equals gas generated.

1.44 cause 4.00 subtract 2.56 is equal to 1.44.
