Two aqueous sulfuric acid solutions containing 20.0 wt% h2so4

(sg = 1.139) and 60.0 wt% h2so4 (sg = 1.498) are mixed to form a

4.00 molar solution (sg = 1.213). taking 100kg of the 20% feed

solution as a basis, calculate the feed ratio (liters 20%

solution/liter 60% solution).

Evaluate this exponential expression,8. (2 + 3)2 – 42
