Which of the following does not indicate that a chemical change may have taken place? a.) energy transfer b.) precipitate formation c.) gas production d.) phase change

The mass in grams of potassium chloride required to prepare this solution is 1.862 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute

= volume of solution in ml

moles of =

Now put all the given values in the formula of molality, we get

Therefore, the mass in grams of potassium chloride required to prepare this solution is 1.862 grams
