sodium hydroxide 0.04 is incorrect

Answer 1

Part 1:
First, calculate the percentage of sodium hypochlorite in the bleach:
(1.2 g / 24 mL) x 100 = 5%

Next, calculate the concentration of sodium hypochlorite:
5 g/100 mL = 5 g/L or 5%

Part 2:
First, calculate the percentage of sodium hydroxide in the bleach:
(0.0096 g / 24 mL) x 100 = 0.04%

The correct concentration for sodium hydroxide is 0.04% (same as the percentage).
