Phosphate baking powder is a mixture of starch, sodium hydrogen carbonate, and calcium dihydrogen phosphate. When mixed with water, phosphate baking power releases carbon dioxide gas, causing a dough or batter to bubble and rise.
2 NaHCO3(aq) + Ca(H2PO4)2(aq) →Na2HPO4(aq) + CaHPO4(aq)+2 CO2(g) + 2 H2O(l)
If 2.5 L of CO2 is needed for a cake and each kilogram of baking power contains 168 g of NaHCO3, how much baking powder must be used to generate this amount of CO2? The density of CO2 at baking temperature is about 1.20 g/L.
Answer in units of g.
