Question

If 0.435 g of KMnO4 is dissolved in enough water to give 250 ml of solution, what is the molarity of

KMnO4?

ASAPP PO!! thankyouu!!!!!

Answer 1

M = 0.011 mol/L

Step-by-step explanation:

Molarity = n/V,
n: No. of moles
V: volume in liters

n of KMnO4 (Molar mass = 158 g/mol) = 0.435/158 = 0.00275 moles

Molarity (M) = 0.00275/0.25 = 0.011 mol/L
