Calculate the amount of water required to prepare 500g of 2.5% solution of sugar

To calculate the amount of water required to prepare a 2.5% solution of sugar weighing 500g, we need to follow these steps:

Step 1: Convert the percentage concentration to a decimal. To do this, divide the percentage by 100. In this case, 2.5% becomes 0.025.

Step 2: Calculate the mass of sugar needed. Multiply the total mass of the solution (500g) by the decimal concentration (0.025). This will give us the mass of sugar required.

Mass of sugar = 500g * 0.025 = 12.5g

Step 3: Calculate the mass of water needed. Since the total mass of the solution is 500g and the mass of sugar is 12.5g, the mass of water can be found by subtracting the mass of sugar from the total mass.

Mass of water = Total mass of solution - Mass of sugar Mass of water = 500g - 12.5g = 487.5g

Therefore, to prepare a 500g 2.5% solution of sugar, you would need 12.5g of sugar and 487.5g of water.
