Answer 2

Calculation of the Mass Fraction of Sugar in the Syrup

To calculate the mass fraction of sugar in the syrup, we need to determine the mass of sugar and the total mass of the syrup.

Given: - Amount of sugar = 1.5 kg - Volume of water = 1 L - Density of water = 1 g/mL

To find the mass of the syrup, we need to convert the volume of water to mass using its density. Since the density of water is 1 g/mL, the mass of 1 L of water is 1000 g.

Now, let's calculate the total mass of the syrup:

1. Mass of sugar = 1.5 kg 2. Mass of water = 1000 g

Total mass of the syrup = Mass of sugar + Mass of water

To find the mass fraction of sugar in the syrup, we divide the mass of sugar by the total mass of the syrup and multiply by 100 to express it as a percentage.

Let's calculate the mass fraction of sugar in the syrup:

Step 1: Convert the mass of sugar to grams: - Mass of sugar = 1.5 kg = 1500 g

Step 2: Calculate the total mass of the syrup: - Total mass of the syrup = Mass of sugar + Mass of water - Total mass of the syrup = 1500 g + 1000 g = 2500 g

Step 3: Calculate the mass fraction of sugar in the syrup: - Mass fraction of sugar = (Mass of sugar / Total mass of the syrup) * 100

Now, let's calculate the mass fraction of sugar in the syrup:

Mass fraction of sugar = (1500 g / 2500 g) * 100

Mass fraction of sugar = 60%

Therefore, the mass fraction of sugar in the syrup is 60%.
