#### Explanation:

Step one: Know the triangle!

Source, yenka (2010)

Now, this is really helpful to me considering that I am the worst at maths. The line in between mass and moles + atomic mass is divide and the line between moles and atomic mass is multiply.

To find how many grammes are in 0.252 mol of copper, you simply follow the triangle and multiply the number of moles with the atomic mass.

So this is:

#"0.252 mol " xx " 63.54 g/mol"# (the molar mass of copper)

#= 16.01208#

#"= 16.0 grams"#

NOTE: If you want to find the atomic mass (Molar Mass) and there is more than one atom in the formula, you must add all the atomic masses together. For example,

#"= 58.44 g/mol"#
