Chemistry Molarity Solution: How many grams of NaOH (MW = 40.0) are there in 35...

🤓 Based on our data, we think this question is relevant for Professor Ilies' class at DREXEL.

Solution: How many grams of NaOH (MW = 40.0) are there in 350.0 mL of a 0.225 M NaOH solution?

Problem

How many grams of NaOH (MW = 40.0) are there in 350.0 mL of a 0.225 M NaOH solution?

Solution

We’re being asked to calculate the mass of NaOH in 350.0 mL of a 0.225 M NaOH solution.


Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters)

In other words:


Molarity(M)=moles of soluteLiters of solution
