Question

a solution contains 30g of sugar in 350g of water calculate the concentration of water​

Answer 1

Answer:

Concentration = mass of solute/mass of solution x 100 = 30/380 = 7.89%

Answer 2

The mass by mass percentage of a solution is given as follows

Mass by mass percentage of a solution = [(Mass of solute) / (Mass of solution)] X 100

where mass of the solution = mass of the solute + mass of the solvent

Here

Mass of solute (sugar) = 30g

Mass of solvent (water) = 350g

Mass of the solution = mass of sugar + mass of solvent = (30 + 350)g = 380 g

Thus, mass by mass percentage of the solution =( 30 / 380) X 100 = 7.8%

Thus, the concentration of the solution is 7.8%.
