How would i go about solving this problem?

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.

The first thing you need to do with problem of this kind is to write the chemical equation. This would help you in calculations later. First, convert how many moles are there in 1.75g of carbon dioxide. Then, from the chemical equation you will know how many moles of sodium bicarbonate formed with 1 mole of carbon dioxide. Then convert the moles of sodium bicarbonate to grams using the molecular weight of the compound. You now have your answer.
