Explanation / Answer

4. The solubility of sugar in water is about 1.8 g/mL at room temperature. If you had a cup of coffee (250 mL) and added 50 packets of sugar to it, would you expect all of the sugar to dissolve? (A typical packet of sugar contains about 3.4 g of sugar) Show your work!

Given that;

The solubility of sugar in water = 1.8 g/mL at room temperature

A packet of sugar contains about 3.4 g of sugar

Thus total amount of sugar = 50*3.4 = 170 g

The amount of sugar which is soluble in 250 ml= 1.8 g/mL *250 ml

= 450 g

Here the amount of sugar is less than 450 g thus 50 packets of sugar are soluble in 250 ml coffee
