Question

What is the molarity of a solution of K3PO4 made by mixing 0.26 mol of potassium

phosphate with water up to 0.35L?

Answer 1

Given :

0.26 mole of
`K_3PO_4` and 0.35 L of water.

To Find :

The molarity of a solution of
`K_3PO_4` made by mixing 0.26 mole of potassium

phosphate with water up to 0.35 L .

Solution :

We know, molarity is given by :

`M = (number \ of \ moles )/(Volume \ in \ Liter)\\\\M = (0.26)/(0.35)\ M\\\\M = 0.743 \ M`

Therefore, the molarity of
`K_3PO_4` solution is 0.743 M.
