Question

What mass of potassium nitrate would be needed to produce saturated solution of potassium nitrate in 50g of water at 313k?

Answer 1

Solubility of potassium nitrate at  313K = 62/100

100 g of water contains potassium nitrate = 62 g

50 g of water contains potassium nitrate  = 62/100 X 50 = 31g

Thus, 31 g potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 g of water at 313 K.

Answer 2

Answer:

Here is your answer......

Explanation:

Solubility of potassium nitrate at  313K = 62/100

100 g of water contains potassium nitrate = 62 g

50 g of water contains potassium nitrate  = 62/100 X 50 = 31g

Thus, 31 g potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 g of water at 313 K.
