i) Mass of CO2 formed = 2.241 g Molar mass of CO2 = Atomic mass of C + 2 (Atomic mass of O) = 12 + 2 (16) g/mol = 44 g/mol Thus, moles of carbon dioxide formed

0.05mole

Explanation:

Given parameters:

Mass of Carbon dioxide formed  = 2.241g

Molar mass of Carbon dioxide  = 44g/mol

Unknown:

Number of moles of carbon dioxide  = ?

Solution:

To solve this problem, we use the expression below:

 Number of moles  =  

  Now, insert the parameters and solve;

 Number of moles =   = 0.05mole
