Practice Calculating Molar Masses


Calculate the molar masses for each formula using paper and pencil, then check your answer using the Java applet located below. It won't do you any good if you get the answers from the applet. You need to practice calculating them yourself, because the applet won't be available on a test.

  1. CO2

  2. HNO3

  3. CCl4

  4. Na2SO4

  5. C12H22O11

  6. NH4OH

  7. Cu(NO3)2

  8. (NH4)3PO4

  9. CH3COOH

  10. NaHSO3
