# Calculate the percent by mass of solute in each of the following solutions. 14 g of potassium chloride dissolved in 12.5 g of water 14 g of potassium chloride dissolved in 25.0 g of water 14 g of potassium chloride dissolved in 37.5 g of water 14 g of potassium chloride dissolved in 50.0 g of water

Interpretation Introduction

(a)

Interpretation:

The mass percent of solute in the given solution is to be calculated.

Concept Introduction:

There are many ways to determine the concentration of a solution. One of the methods is mass percentage. Mass percentage is defined as the total mass of solute divided by the total mass of the solution, multiplied by 100 to get the percentage.

The formula for the calculation of mass percentage is,

Mass%=massofsolutegmassofthesolutiong×100.

Explanation

The formula for the calculation of mass percentage is,
