Question

What is the molarity of a solution containing 5 moles of solute in 250 milliliters of solution?

Answer 1

To calculate the molarity, divide the moles of solute by the volume of the solution in liters. In this case, the molarity of the solution is 20 M.

Step-by-step explanation:

Molarity is a measure of the concentration of a solute in a solution, and it is expressed as moles of solute per liter of solution. To calculate the molarity, we need to convert the volume of the solution from milliliters to liters:

Molarity (M) = moles of solute / volume of solution (in liters)

In this case, we have 5 moles of solute and 250 milliliters of solution. To convert milliliters to liters, we divide by 1000:

Volume of solution = 250 milliliters / 1000 = 0.25 liters

Now we can calculate the molarity:

Molarity (M) = 5 moles / 0.25 liters = 20 M

Therefore, the molarity of the solution is 20 M.

Answer 2

Answer: The molarity of a solution is 20 M

Step-by-step explanation:

Molarity is defined as the number of moles present in one liter of solution.

Mathematically,

`\text{Molarity of the solution}=\frac{\text{Moles of solute}* 1000}{\text{Volume of solution (in mL)}}`

We are given:

Moles of solute = 5 moles

Volume of solution = 250 mL

Putting values in above equation, we get:

`\text{Molarity of solution}=(5* 1000)/(250)=20M`

Hence, the molarity of a solution is 20 M
