Question

A boy wanted to make candy from crystallized sugar. He dissolved 300 g of sucrose in 75g of water at 100 degrees Celsius. To the nearest gram, how much sugar crystallized out of the saturated solution when it cooled to 20 degrees Celsius?

Answer 1

Answer:

The answer is 147.1 grams

Explanation:

Since, You/Question didn't mention the solubility of sucrose/100g,

I'm assuming that it should be 203.9g/ 100gm of ${H_2}O$

75g of water at 20°C can hold sucrose of

$\frac{203.9g \times 75}{100} = 152.92g \: of \: sucrose$

To calculate the sucrose that is crystallized out is

Initial Sugar - Remaining in the solution

$300g - 152.9g = 147.1 \: gm$

Therefore the amount of sucrose crystallized out the saturated solution whezn it cooled to 20° is 147.1 gm
