Step 1

Given,

Density of solution = 1.67 g/mL

Mass percent of sulfuric acid in the solution = 75 %

Volume of solution = 400 mL

Mass of solution can be calculated as:

Step 2

The mass of sulfuric acid can be calculated using the mass percent formula: help_outlineImage TranscriptioncloseMass of sulfuric acid % mass x 100% Mass of solution Mass of sulfuric acid x 100% 75% 668 g 75% X 668 g Mass of sulfuric acid 100% Mass of sulfuric acid 501 g fullscreen
Step 3

Therefore, moles of sulfuric ac... help_outlineImage TranscriptioncloseMolar mass of H2SO4 (2x1)32 (4x16) 98 g/mol Mass Moles Molar mass 501 g Moles 98 g/mol Moles 5.11 mol fullscreen
