The amount of water needed to prepare a 0.50 molal solution using 0.50 moles of sodium chloride is 1L.
How to calculate volume?
The volume of a solution can be calculated using the following formula:
Volume = no of moles ÷ molarity
According to this question, 0.50 molal solution is used to prepare 0.50 moles of sodium chloride. The volume of the solution is calculated as follows:
Volume = 0.50 moles ÷ 0.5M
Volume = 1L
Therefore, the amount of water needed to prepare a 0.50 molal solution using 0.50 moles of sodium chloride is 1L.
