Answer:
110.25grams
Explanation:
The balanced chemical equation is as follows:
H2SO4 + 2NaOH → Na2SO4 + 2H20
Based on the balanced chemical equation of the reaction given above, 1 mole of sulphuric acid (H2SO4) is required to react with 2 moles of sodium hydroxide (NaOH).
Hence, if 1 mol of H2SO4 is needed to react with 2 moles of NaOH
Then, 2.25mol of NaOH will be required to react with;
= 2.25/2
= 1.125mol of H2SO4
Using the formula, mole = mass/molar mass, we can convert the molar value of H2SO4 to its mass value.
Molar mass of H2SO4 = 1(2) + 32 + 16(4)
= 2 + 32 + 64
= 34 + 64
= 98g/mol
Therefore, mole = mass/molar mass
1.125 = mass/98
mass = 98 × 1.125
mass = 110.25grams of H2SO4
