HOW MANY GRAMS OF SALT ARE REQUIRED TO PREPARE 300 G OF 15% SALT SOLUTION?

HOW MANY GRAMS OF WATER ARE NEEDED?

displacement HCI+Mg(OH)2

To calculate the amount of salt required to prepare a 15% salt solution, you need to know the desired total weight of the solution and the desired concentration of salt.

In this case, the desired total weight is 300 grams, and the desired concentration is 15%.

Step 1: Calculate the amount of salt needed.
To find the amount of salt needed, you can use the formula:
Amount of salt = Total weight of solution x desired concentration

Amount of salt = 300 g x 15% = 0.15 x 300 g = 45 g

Therefore, 45 grams of salt are required to prepare a 300 g of 15% salt solution.

To calculate the amount of water needed, you need to subtract the weight of the salt from the total weight of the solution.

Step 2: Calculate the amount of water needed.
Amount of water = Total weight of solution - Amount of salt

Amount of water = 300 g - 45 g = 255 g

Therefore, 255 grams of water are needed to prepare a 300 g of 15% salt solution.
