Question

If you have 3.16 moles of a particular atoms, using Avogadro's Number, how many totalatoms do you have?

Answer 1

Step 1 - Understanding Avogadro's number (mole)

By definition, one mole is a number that corresponds to 6.02*10^23 unities of something. This number is called Avogadro's number.

Let's say, for example, we have one mole of chairs. How many chairs would we have? Exactly 6.02*10^23 chairs.

Step 2 - Using this information to solve the exercise

To solve the exercise, we can set the following proportion:

`\begin{gathered} 1\text{ mole ----- 6.02}*10^(23)\text{ atoms} \\ 3.16\text{ moles ---- x} \\ \\ x=(3.16*6.02*10^(23))/(1)=1.90*10^(24)\text{ atoms} \end{gathered}`

The total number of atoms we would have would be thus 1.90*10^24 atoms.
