How many moles of are in 179 mL of a 3.0 M of CaCl2 solution?

Answer: 0.537 moles

Explanation:

Hello, Let's first explain the term molarity

---> Molarity is the most commonly used term to describe the concentration of a solution. It is equal to the moles of solute divided by the liters of solution.

---> The solute is defined as the substance being dissolved, while the solvent is the substance where the solute is dissolved (usually water).

---> The solution is the combination of the solute and the solvent.

Molarity = moles of solution/Liters of

solution

Parameters given are

Volume (V) = 179ml of CaCl2 solution

Molarity = 3.0m

Therefore,

Molarity = number of moles of CaCl2 solution / Volume of CaCl2 in Liters (eqn 1)

First, convert 179ml to liters

1ml = 0.001L

179ml = ?

179ml = 179ml x 0.001L

= 0.179L

From (eqn 1)

Let the number of moles of CaCl2 solution be M

=> 3 = M/0.179

M = 0.179 x 3

= 0.537 moles

Hence the number of moles in 179ml of CaCl2 solution yields 0.537 moles
