Ans: Moles of CO2 = 0.25 moles
<u>Given:</u>
Mass of CO2 = 11 g
<u>To determine </u>
Moles of CO2
<u>Explanation:</u>
Moles = mass/molecular mass
Molecular mass of CO2 = 44 g/mol
Moles of CO2 = 11 g/44 g.mol-1 = 0.25 moles
The atomic number of H2O is 18 hence it contains 18 protons. Hope this helps.
