II. EXERCISE: Directions: Solve the problems and show your complete solution.
1. What volume of 23% m/v solution contains 453 g of solute?
2. Find the amount of solute to make 0.5 L of a 39% m/v solution.
1. 453 = 100%
? = 23%
= 453 × 23/100 = 104.19ml
2. 0.5 L = 39%
500ml = 39%
? = 100%
= 500×100/39
= 1282.1g
