How many grams of KCl must be added to 75g of water produce a solution

1.	How many grams of KCl must be added to 75g of water produce a solution that is 2.25 molal
Answer» Answer: 12.57 g of KCl Explanation: MOLALITY = weight of KCl × 1000 / molar mass of KCl × 75 g H2O = X × 1000/74.5×75 = 2.25 so, X = 12.57 mark, me BRAINLIEAST

How many grams of KCl must be added to 75g of water produce a solution that is 2.25 molal

Answer»

Answer:

12.57 g of KCl

Explanation:

MOLALITY = weight of KCl × 1000

/ molar mass of KCl × 75 g

H2O

= X × 1000/74.5×75 = 2.25

so, X = 12.57
