Question

What is the volume (in liters) of a 0.25 Molar solution made from 0.53 moles of potassium bromide? Round your answer to the nearest 0.01 and include units properly abbreviated, but NOT substance!

Answer 1

Here we have a 0.25 M solution.

Remember M or molarity is the moles per liters of solution.

Solute = potassium bromide KBr

0.25 mol/L: 0.25 moles of KBr ------- 1 L of solution

Now, let's find the volume:

0.25 moles of KBr ------- 1 L of solution

0.53 moles of KBr ------- X

X = 2.12 L

Answer: V = 2.12 L
