Question

how much potassium chlorate would dissolve in 200g water at 20c grade 7​

Answer 1

Answer:

Given that the solubility of sodium chloride is 36 grams per 100 grams of water. Which of the following solutions would be considered supersaturated? A. dissolve 5.8 moles of NaCl in 1 L of water B. dissolve 1.85 moles of NaCl in 300 ml of water C.

Answer 2

The answer is 61.275

GIVEN

Mass of water = 200 grams

TO FIND

The solubility of potassium chlorate at 20°C

SOLUTION

The above problem can be simply solved as follows;

Solubility of a substance = (Mass of solute/mass of solvent) × 100

Mass of potassium cholrate = 122.55 g/mol

Solubility = (122.55/200) × 100

= 61.275

Hence, The answer is 61.275
