Respuesta :
72.0 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
Answer:
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)
