A procedure calls for 100cm³ of 20.0% of H2SO4 by weight having densit...
98% by weight of solution means 98g of H2SO4is present in 100g of solution.
Volume of solution =density of solution
mass of solution =(1.8�1000)g/L 100g
Volume of solution =181L
Per cent H2SO4w/v of solution = molarity =volume of solution (in L)number of moles of H2SO4
Molarity =volume of solution
given mass of H2SO4/ molar mass of H2SO4
Molarity =1/18
98/98
=18M

Calculating the amount of concentrated acid needed:
- Let x be the volume of concentrated acid needed.
- The amount of H2SO4 in the concentrated acid = 0.98x.
- The amount of H2SO4 in the final solution = 0.20 * 100cm³ = 20cm³.

Setting up the equation:
- 0.98x + 0 = 0.20 * 100
- 0.98x = 20
- x = 20 / 0.98
- x ≈ 20.41cm³

Calculating the volume of water needed:
- Volume of water needed = 100 - 20.41
- Volume of water needed = 79.59cm³

Final steps:
- Using the densities of the two acids, we can calculate the amount of each needed to achieve the desired concentration.
- Let y be the volume of the diluent (water).
- 1.84 * 20.41 + 1.00 * y = 1.14 * 100
- Solving for y, we get y ≈ 79.59cm³.

Therefore, approximately 20.41cm³ of concentrated acid and 79.59cm³ of water need to be mixed to prepare 100cm³ of 20.0% H2SO4 by weight.
