What is the use of density in the calculation of percentage by mass?
Answers
~~~~~~~~~~~~~~~~~~
First, the direct method requires recording the total mass of solution, and then evaporating off the solvent. The solid left behind is the solute, which is then weighed and used to calculate mass percent. Density can also be used to determine the mass percent of an unknown concentration.

Answer:
Explanation:
Density can also be used to determine the mass percent of an unknown concentration. First, a series of standard solutions are prepared, with a range of solute amounts. Select standards that range in concentration from no solute, to the maximum solubility of the solute.
Mass percentage:
A concentration or a component in a certain combination can be expressed as mass percentage. The mass percentage that indicates the mass of solute contained in a given mass of solution may be used to characterise the composition of the solution. In terms of mass or moles, the solute's concentration is stated. The grammes of solute per gramme of solution, multiplied by 100 to obtain the percentage, is how a solution's mass percent is defined.
The Mass per cent formula is expressed as solving for the molar mass also for the mass of each element in 1 mole of the compound. You can determine the mass percentage of each element with these masses.
