🤓 Based on our data, we think this question is relevant for Professor Petrovich's class at NCSU.

Solution: How many moles of solute particles are present in 1 mL of each of the following aqueous solutions? (c) 0.08 M pyridine (C5H5N)

Problem

How many moles of solute particles are present in 1 mL of each of the following aqueous solutions?
 
(c) 0.08 M pyridine (C5H5N)

Solution

We’re being asked to calculate the moles of pyridine (C5H5N) present in 1 mL of a 0.08 M pyridine 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
