Sagot :

Explanation:

Molarity, or concentration in amount of matter (mol/L), is the ratio between the amount of matter in the solute (n) and the volume of the solution in liters (V): M = n/V

Here we have:

m = 166 g of KI (solute)

V = 1000 mL = 1L (solution)

So we need to transform 166 g of KI into moles. We use the following formula:

n = m/MM

MM of KI is 166 g/mol

n = 166/166

n = 1 mol

So:

M = 1/1

M = 1 mol/L

Answer: M = 1 mol/L
