Example:
How many moles of Sodium (Na) are in 1 serving
of Swiss Miss hot chocolate?
The nutrition facts say that there are 170 mgs of
sodium in a serving.
Convert mg to g. 170mg/ 1000= 0.17 g
Find the molar mass of Na
The periodic table says that the molar mass of Na is
22.99g/mol
Set up your equation
0.17g Na X 1 mole Na = 0.17 = .0074 moles Na
1
22.99 g Na 22.99
