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? 12.0 72.0 216 528

12.0

Explanation:

Hi, the reaction is:

H2O + CO2 --> H2CO3

Analyzing the reaction result:

To produce 1 mole of H2CO3 we need 1 mole of H2O for every mole of CO2.

So, the Stoichiometric ratio between H2O and CO2 is 1:1.

Applying the formula:

.n = m/M

Where:

.n = number of moles

.m = mass in grams

M = grams per mol

e

.n = 528/ 44.01 = 11.9972 =12 mol

es of C02

The Stoichiometric ratio IS 1:1 , so the number of moles of water used are the same. (12)
