22) (7 points ) How m nts) How much 8N H2SO4 can I make with 984 mL of a stock solution that has an essay of 79% and sp.gr of 1.84? 23) (6 points) I want to make three different solutions from 50% acetic acid in water. I want to make 10 ml of a 4% solution, 20 ml of a 1% solution and 100mL of a 0.05 % solution. How much 50% acetic acid and water should I put in each of the three tubes.

Answer 1

DATED and x be 4 of sol" Let a be the amount aloracetic acid the amount of wath Tomake lomL of so x + x₂ = 10 - 0.04 0.504 x,+22 0.50 = 0.04 0.5% = 0.04(10) 24 = 9.2 mm 0.8mL of sot of acetic acid and 92mL of notes For 20mL of the solution += 20 0.524 = 0.01 0.5X1 = 0.2 7.75 -0.4mL H = 19.6mi oume of soy of acetic acid and 19.6 mL of water 80 - For 100mL of 0.05% 2+2 =100 0.5x10.05 0.50 = 0.05 H, = of mL M = goig mL so oil ml of soy of acetic acid and ggog mL of water.
