What is the molarity of a solution that contains 2.634 mol KCI in 25.2 L solution?O a. 0.105O b. 0.00141O c. 7.73O d. 105
Vikentia [17]

Explanation:

To solve this question, we need to use the following formula:

M = n/V

So:

M = ??

n = 2.634 mol

V = 25.2 L

M = 2.634/25.2

M = 0.105 mol/L

Answer: a. 0.105

What is the molarity of a solution prepared by dissolving 36. 0 g of naoh in enough water to make 1. 50 l of solution?
Vlada [557]

0.6 mol / L is the molarity of a solution prepared by dissolving 36. 0 g of NaOH in enough water to make 1. 50 l of solution.

The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another term for molarity.

The ratio employed to indicate the solution's concentration is called its molarity. Understanding a solution's molarity is important since it allows you to determine the actual concentration as well as whether the solution is diluted or concentrated.

Amount of NaOH = 36. 0 g

Amount of water = 1. 50 L

1 mol of NaOH = 40 g,

Moles of NaOH = 36. 0 / 40 g = 0.9 mol NaOH

Molarity of a solution = moles of solute / Liters of solution

Molarity of a solution = 0.9 / 1.50

Molarity of a solution = 0.6 mol / L
