Question

How many liters of water would you need to add to 4.36 moles of NaCl to create a 9.4 M solution?

Answer 1

0.46 L

Step-by-step explanation:

In order to solve this problem we need to keep in mind the following definition of molarity:

• Molarity = Number of moles / liters

We now input the given number of moles and molarity:

• 9.4 M = 4.36 mol / liters

And calculate how many liters are required:

• liters = 4.36 mol / 9.4 M

• liters = 0.46 L
