Question

Calculate the no of Ca 2+ , PO 3- and total no. Of ions present in hundred ml solution of 1 mole Ca(PO4) 2

Answer 1

Answer:

Did you mean 100ml 1 Molar soln? if yes, I can help you with that.

Explanation:

Molarity = No of moles / Vol in Litres

therefor, No of moles = M x V = 1 x 0.1  (since 100ml = 0.1 Ltre)

= 0.1 moles of Ca3(PO4)2 is there.

therefore number of Ca2+ = 3 x 0.1 = 0.3 moles

number of PO4 3- = 2 x 0.1 = 0.2 moles
