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
(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
The formula for the calculation of mass percentage is,
