Question

The concentration of KIO3 in solution A is 0.04 M. Calculate the number of moles of potassium iodate in 1 mL of this solution.

Answer 1

Number of moles of KIO₃ = 4.0×10⁻⁵ mol

Step-by-step explanation:

Given data:

Concentration of solution = 0.04 M

Volume of solution = 1 mL

Number of moles of KIO₃ = ?

Solution:

Molarity = concentration

Molarity = number of moles / volume in L

We will convert the volume into L.

1 mL×1 L /1000 mL

0.001 L

Now we will put the values in formula,

0.04 M = number of moles / 0.001 L

Number of moles = 0.04 M ×0.001 L

Number of moles = 4.0×10⁻⁵ mol
