To prepare 480 mL of a 1:20 solution using a 1:10 solution and a 1:50 solution, it requires 3 parts of 1:10 solution and 5 parts of 1:50 solution.
Total volume = 480 ml
Concentrations:
• 1:20 = 1/20 = 0.05
• 1:10 = 1/10 = 0.1
• 1:50 = 1/50 = 0.02
On solving, 0.05 – 0.02 = 0.03
0.1 – 0.05 = 0.05
Total = 0.03 + 0.05 = 0.08
Therefore,
480 * (0.03 / 0.08) = 180 (3 parts)
480 * (0.05 / 0.08) = 300 (5 parts)
Total = 180 + 300 = 480 / 8 = 60 = 1 part
