Mole Conversion Skills Practice Worksheet
1. Calculate the number of molecules in 210 grams of water.
2. If you have 6.25 x 1024 molecules of sulfur tetrafluoride, how many grams do you have?
3. Define what a mole is. Don’t give a number, give a definition in words.
4. What is the mass of 3.45 moles of aluminum sulfate?
5. Consider zinc acetate and find its “formula mass” and its “molar mass”. Include units for each.
6. If you have 245 grams of lithium carbonate, how many moles do you have?
7. How many gold atoms do you have if you have 400 grams of gold?
