Your science teacher needs to make more of a salt-water mixture. The concentration of the mixture that is needed is 35 grams of salt in 1,000
milliliters of water. How many grams of salt will be needed to make 1,500
milliliters of the salt water?

52.5 g of the salt

Explanation:

From the question given above, we were told that concentration of the mixture that is needed can be obtained as by dissolving 35 g of salt in 1000 mL of water.

Thus, we can obtain the mass of the salt needed to make 1500 mL of the salt water mixture as follow:

35 g of salt dissolves in 1000 mL of water.

Therefore, Xg of the salt will dissolve in 1500 mL of water i.e

Xg of salt = (35 × 1500)/1000

Xg of salt = 52.5 g

Thus, 52.5 g of the salt is needed to make 1500 mL of the salt water mixture.
