Question

How much of sugar dissolve in 100 g of water at a)30 b)100 ​

Answer 1

Answer:

$100g$

By comparison, in an unsaturated solution, the rate at which solid particles are dissolved exceeds the rate at which dissolved particles reform the solid, which means that the solution can dissolve more solute than what is already dissolved.

In your case, adding 180 g of sugar to 100 g of water will produce a saturated solution. Use this as a conversion factor to determine the solubility of sugar in 50 g of water at 0∘C

This means that adding 90 g of sugar to 50 g of water at 0∘C will produce a saturated solution.

Now, you want to add 100 g of sugar in 50 g of water. Since you can only hope to dissolve 90 g at this temperature, your resulting solution will contain undissolved sugar.

Therefore, adding 100 g of sugar to 50 g of water at 0∘C will produce a saturated solution that contains 90 g of dissolved sugar and 10g of undissolved.

Answer 2

Answer:

30

Explanation:

because 100 gram is at one cup
