Question
A student plans to make a 100 mL 1.00 N H₂SO₄ solution. The materials available in the lab are 98% (by weight) H₂SO₄ (liquid) with a density of 1.83 g/mL and analytical grade (close to 100% pure) Na₂CO₃ (powder). Describe how the solution should be made. Must show your calculations to support each step.

Expert Solution
Step 1: Mass of sulfuric acid calculation.

It is required to prepare 100 mL of 1 N H2SO4 solution.

So, no. of gram equivalents of H2SO4 present = (100*1)/1000 = 0.1

Equivalent weight of H2SO4 = 49 

So, Mass of H2SO4 needed = 0.1*49 = 4.9 grams
