What is the percent by mass of the solute of a solution made by dissolving 29 grams of sodium lithium chloride in water which has a density of the solution of 1.00 grams/ml, to a final volume of 202 ml solution?
The percent by mass formula is expressed as:
From the volume and density, we can find the mass of solution using this formula:
Rearranging the formula to find mass:
Plugging in the values into percent by mass formula:
