Question

How much KNO3 must be

dissolved in 50 g of water to
yield a saturated solution at
50°C?

Answer 1

Step-by-step explanation:

This is the simple answer of this question with respect to 60 degree temperature but question requirement is 50 so we will do it according to 50 degree temperature

Answer 2

The solubility of KNO3 in water increases with temperature. At 50°C, the solubility of KNO3 in water is 34 g/100 g water. This means that at 50°C, 100 g of water can dissolve up to 34 g of KNO3.

To find out how much KNO3 must be dissolved in 50 g of water to yield a saturated solution at 50°C, we can set up a proportion:

34 g KNO3/100 g water = x g KNO3/50 g water

where x is the amount of KNO3 that must be dissolved in 50 g of water.

Solving for x, we get:

x = (34 g/100 g) x 50 g

x = 17 g

Therefore, 17 g of KNO3 must be dissolved in 50 g of water to yield a saturated solution at 50°C.
