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 528g of co2. how many moles of water are used in this reaction?

Hello!



The mole to mole or stoichiometric ratio between carbon dioxide and water are 1:1 from above equation. That means we need 1mole of water for every mole of CO2. and given the value of CO2 the reaction uses we can solve for the number of moles of CO2 and then we need that same amount of moles of water. 

So 528g/44.01g/mol = 11.99727 or approx 12moles of CO2 used so therefore we need 12moles of H2O as well to complete the reaction. 

Hope this helps. Any questions please just ask. Thank you kindly.
