Answer:
118.296 ml of water
Explanation:
Given that;
v/v% concentration = volume of solute/volume of solution * 100
volume of solution = 8 oz
v/v% concentration = 50%
50 = volume of solute/8 * 100
volume of solute = 50 * 8/100
volume of solute = 4 oz
Volume of water needed = Volume of solution - volume of solute
Hence
8 oz - 4 oz
Volume of water needed = 4 oz
1 oz = 29.574 ml
4oz = 4oz * 29.574 ml/1 oz
= 118.296 ml of water
