What is concentration of a solution that contains 45 grams sugar in 500 gram solution.explain?

To find the concentration of a solution in grams per 100 grams, you can use the formula: ((\text{mass of solute} / \text{mass of solution}) \times 100). In this case, the mass of the solute (sugar) is 45 grams, and the total mass of the solution is 500 grams. Therefore, the concentration is ((45 , \text{g} / 500 , \text{g}) \times 100 = 9%). This means the solution has a concentration of 9% sugar by mass.
