Question

What is the molarity of a solution of 3 moles (mol) of febr3 in one divided by two l water?

a. 3 mol divided by 0.5 l
b. 2 l divided by 3 mol
c. 0.5 l divided by 3 mol
d. 3 mol divided by 2l

Answer 1

The molarity of the solution is 6 mol/L.

Step-by-step explanation:

The molarity of a solution is defined as the number of moles of solute per liter of solution. In this question, we are given that there are 3 moles of FeBr3 and a volume of 0.5 liters of water. To find the molarity, we divide the number of moles by the volume:

Molarity = (Number of moles)/(Volume)

Molarity = 3 mol / 0.5 L

Molarity = 6 mol/L
