The molar mass of carbon dioxide (co2) is 44.01 g/mol. the molar mass of water (h2o) is 18.01 g/mol. a reaction uses 528 g of co2. how many moles of water are used in this reaction?

The reaction that results from this is:

H2O + CO2 --> H2CO3

Stoichiometric ratio between water and CO2 is 1:1. So we can say that for every Mole of CO2, we need 1 Mole of water to produce 1 Mole of H2CO3. Thus as n=m/M we can find n = 528/44.01 = 11.997 ~ 12Mol.

therefore, we need 12 moles of water.

Sorry i dont understand the question can you rephase it?
