1 Mole of Particles What are the conversion factors?

Converting Moles and Grams Aluminum is often used for the structure of light-weight bicycle frames. How many grams of Al are in 3.62 moles of Al? a

1 mole Al = 27.0 g Al

Conversion factors for Al 27.0g Al or 1 mol Al 1 mol Al 27.0 g Al

1 mole Al = 27.0 g Al Conversion factors for Al 27.0g Al or 1 mol Al 1 mol Al 27.0 g Al 3.62 moles Al

1 mole Al = 27.0 g Al Conversion factors for Al 27.0g Al or 1 mol Al 1 mol Al 27.0 g Al 3.62 moles Al 27.0 g Al 1 mole Al = 97.7g Al

A can of diet cola contains about mg of the artificial sweetener aspartame (Nutra-Sweet) formula C 14 H 18 N 2 O 5 is used to sweeten diet foods, coffee and soft drinks. How many moles of aspartame are present in a can of diet cola?

14(12.0) + 18(1.0) + 2(14.0) + 5(16.0) = 294g/mol
