Question

What is the volume of a 6.2 M potassium chloride solution that contains 18.25 mols of solute? Show your work, please

Answer 1

The potassium chloride solution has a volume of 2.94 L

Step-by-step explanation:

Step 1: Data given

The potassium chloride (KCl) solution has a molarity of 6.2 M

This potassium chloride solution contains 18.25 moles

Step 2: Calculate the volume

Molarity = Number of moles / volume (in L)

6.2 M means we have 6.2 moles per 1 liter

Since we do not have 6.2 moles but 18.25 moles, the volume will be more than 1 liter.

Volume solution = Number of moles KCl / molarity soluiton

Volume solution = 18.25 moles / 6.2 M

Volume solution = 2.94 L

The potassium chloride solution has a volume of 2.94 L

Answer 2

The answer to your question is Volume = 2.94 L

Step-by-step explanation:

Data

Concentration = 6.2 M

Number of moles = 18.25

Volume = ?

Process

1.- Use the Molarity formula to solve this problem

Molarity = Number of moles / Volume

- Solve for volume

Volume = Number of moles / Molarity

2.- Substitution

Volume = 18.25 / 6.2

3.- Simplification

Volume = 2.94 L
