NaOH + CO2 ---> NaHCO3
if 126 g of NaHCO3 are produced, how many grams of NaOH would be required to drive this reaction??

Mass of NaOH required= 60 g

Explanation:

Given data:

Mass of NaHCO₃ = 126 g

Mass of NaOH required = ?

Solution:

Chemical equation:

NaOH + CO₂   →   NaHCO₃

Number of moles of NaHCO₃:

Number of moles = mass/ molar mass

Number of moles = 126 g/ 84 g/mol

Number of moles = 1.5 mol

Now we will compare the moles of NaHCO₃ and NaOH.

                   NaHCO₃       :        NaOH

                        1               :            1

                      1.5              :            1.5

Mass of sodium hydroxide:

Mass = number of moles × molar mass

Mass = 1.5 mol × 40 g/mol

Mass = 60 g
