Mass % = (mass of solute /Mass solution) * 100
= (20 /800) * 100
=2.5 %
Hence, mass % is 2.5
Answer:
The answer is: the mass percent of solute is 2.5 %
Explanation:
A solution has two components, the solvent and the solute. The solvent is present in greater quantity usually. If 780 g of 800 g are of eater, that means water is the solvent, therefore 20 g are solute. To find the percentage, use the next equation:
% of solute = (g of solute/g of total solution)*100
% of solute = (20/800)*100 = 2.5
