A **mole** refers to 6.022⋅1023 items. H2O has 2 hydrogen **atoms** and **1** oxygen
**atom**...so a total of 3 **atoms** in each H2O . Therefore (6.022⋅1023)⋅ (3 **atoms**) =
18.066⋅1023. Then we need to change the answer into proper scientific notation
: 18.066⋅1023=1.8066⋅1024. Lastly, change to the proper number of significant

For example, the mean molecular weight of water is 18.015 atomic mass units (
amu), so **one mole** of water weight 18.015 grams. Key Terms. mole: The amount
of substance of a system that contains as **many** elementary entities as there are
**atoms** in 12 g of carbon-12. The chemical changes observed in any reaction
involve ...

The chemical formula for water is H2O which means that every molecule of water
has 2 **atoms** of hydrogen (H) and one **atom** of oxygen (O). Here comes the key
part. From the Periodic Table of Elements, one sees that **one mole** of hydrogen
**atoms** weighs 1 gram while **one mole** of oxygen **atoms** weighs 16 grams. What is

0.450 **mole** (or gram) of Fe contains **how many atoms**? 0.200 **mole** (or gram) of H
2O contains **how many molecules**? When the word gram replaces **mole**, you
have a related set of problems which requires **one** more step. So keep in mind
that there are 4 example problems just above. Calculate the number of **molecules**

Introduction to the idea of a **mole** as a number (vs. an animal) ... For your
amusement - it is a lot easier to weigh out **1** gram of a bunch of **atoms** or
**molecules** for a lab experiment than it is to find a single **atom**/**molecule** and work
with it in .... It is **much** easier to handle numbers like "6" than to talk about 3,61*10
