Calculate the mass percent, % (m/m), for the solute in each of the following solutions.
12 g of sugar in 250 g of tea with sugar (solution)
Express your answer using two significant figures.
To calculate the mass percent of the solute (sugar) in the solution, we need to divide the mass of the solute by the mass of the solution and multiply by 100.
Mass percent (m/m) = (mass of solute / mass of solution) × 100
Given:
Mass of sugar = 12 g
Mass of tea with sugar = 250 g
Mass percent (m/m) = (12 g / 250 g) × 100
Mass percent (m/m) = 0.048 × 100
Mass percent (m/m) = 4.8
Therefore, the mass percent of the solute (sugar) in the solution is 4.8%.
To calculate the mass percent of the solute in a solution, we use the formula:
Mass percent = (mass of solute / mass of solution) x 100
Given:
Mass of sugar (solute) = 12 g
Mass of tea with sugar (solution) = 250 g
Substituting these values into the formula, we have:
Mass percent = (12 g / 250 g) x 100
Calculating the division:
Mass percent = 0.048 x 100
Mass percent = 4.8%
Therefore, the mass percent of the solute (sugar) in the solution is 4.8%.
To calculate the mass percent, % (m/m), of the solute in a solution, you need to divide the mass of the solute by the total mass of the solution, and then multiply by 100.
First, let's calculate the total mass of the solution. The solution is composed of 12 g of sugar and 250 g of tea with sugar. Therefore, the total mass of the solution is:
12 g (sugar) + 250 g (tea with sugar) = 262 g
Next, let's calculate the mass percent of the solute (sugar). Divide the mass of the sugar by the total mass of the solution, and then multiply by 100:
Mass percent = (mass of solute / total mass of solution) x 100
Mass percent = (12 g / 262 g) x 100
Mass percent ≈ 4.58%
Therefore, the mass percent of the solute (sugar) in the given solution is approximately 4.58%.
