Question

Sodium bicarbonate reacts with sulfuric acid to form sodium sulfate, carbon dioxide, and water. calculate the mass od sodium bicarbonate necessary to produce 1.75 g of carbon dioxide gas.

How would i even go about doing this?,

Answer 1

Obtain molar mass of CO2 and NaHCO3 Mass of CO2 divided by molar mass of CO2 gives moles of CO2.
You have 2 moles of CO2 at the end and 2 moles of NaHCO3 at the beginning Now You have moles of NaHCO3 multiply molar mass of NaHCO3 by the moles of NaHCO3 to get only mass of NaHCO3 initial.
