Final answer:
To find the amount of sugar left when a liquid vaporizes, multiply the total mass of the liquid by the percentage of sugar in the liquid.
Step-by-step explanation:
To solve this problem, you can follow these steps:
- Calculate the total mass of sugar in the liquid. In this case, it would be 150 g x 0.45 = 67.5 g.
- When the liquid vaporizes, the sugar will remain behind. So the mass of sugar left would be 67.5 g.
The formula to solve this is: Mass of sugar left = Total mass of liquid x Percentage of sugar present in the liquid.
