Question

If 1.45 moles of Sodium Bromide are added to a 7.5 M solution, what is the volume of the solution made?

Answer 1

0.193 L

Step-by-step explanation:

Another way of writing the question would be: What volume of a 7.5 M Sodium Bromide solution would contain 1.45 moles.

To answer that we can use the definition of molarity:

• Molarity = moles / liters

We input the given data:

• 7.5 M = 1.45 moles / liters

And calculate how many liters are required:

• 1.45 mol / 7.5 M = 0.193 L
