Question

What is the concentration of a solution with a volume of 2.5 liters containing 600 grams of calcium phosphate?​

Answer 1

1.12M

Step-by-step explanation:

Given parameters:

Volume of solution = 2.5L

Mass of Calcium phosphate = 600g

Unknown:

Concentration = ?

Solution:

Concentration is the number of moles of solute in a particular solution.

Now, we find the number of moles of the calcium phosphate from the given mass;

Formula of calcium phosphate = Ca₃PO₄

molar mass = 3(40) + 31 + 4(16) = 215g/mol

Number of moles of Ca₃PO₄ =
`(600)/(215)` = 2.79moles

Now;

Concentration =
`(Number of moles )/(volume )`

Concentration =
`(2.79)/(2.5)` = 1.12M
