Answer 2

Answer:

Molarity of diluted solution​ is 1.29mol/litre.

Explanation:

The relationship between the volume of a solution and the moles of a solute is referred to as molarity. [1] Beginning with moles and volume, mass and volume, or moles and millilitres will allow you to compute molarity. You can find the right answer by entering these factors into the fundamental molarity calculation formula.

To calculate molarity:

Find the number of moles of solute dissolved in solution,

Find the volume of solution in liters, and.

Divide moles solute by liters solution.

Molarity is equal to the number of moles of a solute divided by the volume of the solution in liters. As such, it is written as:

Molarity = moles of solute / liters of solution

Given:

Volume of solution, $V_{1} =2L$

Volume of diluted solution, $V_{2} =28mL$

Molarity of solution, $M_{1}=18M$

$M_{1} V_{1} =M_{2} V_{2}$

$2\times1000\times18=28M_{2} \\\\M_{2}=\frac{2\times1000\times18}{28} \\M_{2}=1.29mol/litre$

Hence, molarity of diluted solution​ is 1.29mol/litre.
