Answer 2

Calculating the Mass of Salt and Water for a 150g 2% Solution

To calculate the mass of salt and water needed to prepare a 150g 2% solution, we can use the formula:

Mass of solute = (percent / 100) * mass of solution

Where: - Mass of solute is the mass of the salt - Percent is the percentage of the solution - Mass of solution is the total mass of the solution

Using the given information: - Mass of solution (water + salt) = 150g - Percentage of salt in the solution = 2%

Calculation

Mass of salt = (2 / 100) * 150g

Mass of salt = 0.02 * 150g

Mass of salt = 3g

Therefore, to prepare a 150g 2% solution, you would need 3g of salt and the remaining mass would be water.

I hope this helps! If you have any other questions, feel free to ask.
