_{Molarity is defined as the number of moles of a compound dissolved in an amount of solvent. It is also known as molar concentration and has a unit mol/L or molar(M)}

Step by step solution

Step 1: Given

Given the mass of KMnO4= 0.0908g

Given volume of solution= 0.500L

The formula we shall use to determine molarity is :

(a) Molarity of a solution = number of moles/volume of solution in L

Again, number of moles = (given mass )/(molar mass )

= 0.0908g/(158.04g/mol)

= 0.000575 mol

Therefore, by substituting the values, we get

Molarity = 0.000575mol/0.500L

=1.15×10^-3 M

(b) The molarity of KMnO4 containing 0.0908g of KMnO4 in 0.500L of solution is 1.15×10^-3 M

=1.15×10-3 M

(b) The molarity of KMnO4 containing 0.0908g of KMnO4 in 0.500L of solution is 1.15×10-3 M
