  1. Chem Catalyst Your lab asks you to add 1.50 mol of sodium chloride to a test tube. How many grams of sodium chloride should you weigh out?

  2. Today’s Agenda: • Catalyst • Class practice- mole conversions • Worksheet practice • Quiz tomorrow!

  3. Conversion: Mass to Moles • Multiply by (1 mol/ molar mass) • Ex: How many moles of iron (III) oxide are contained in 92.2g of Fe2O3?

  4. Summary

  5. Practice: • Calculate the mass, in grams, of 2.50 mol Fe(OH)2 • Find the mass of 3.00 mol of NaCl • Find the number of moles in 0.370 g of Boron. • Calculate the number of moles in 75.0 g of dinitrogen trioxide.
