Converting between multiple units

When converting between multiple units (say between grams and liters of a gas or between number of particles and volume of solution) you must use moles as a stepping stone to get from one to the other.

In other words, there is no direct connection between grams and liters of a gas, however grams can be converted to moles and then moles can be converted to liters of gas.

Let's look at a few example problems:

How many molecules of sucrose (table sugar) are there in a 4.56 L of a 1.08 M solution?
To solve this, we will use the factor label method as before, but will have an extra fraction.

If 36.9 g of neon gas are placed in a balloon at STP, what will the volume of the balloon be?



What is the mass of 3.25x1024mc of sodium acetate?
