Journal Entry:

Write the formulas or names for these compounds Lithium Nitrate, Heptane, Hydrofluoric acid,  Magnesium Flouride,  H₂CO₃, Calcium Acetate,  C₃H₈

Learning Intentions

• You will learn how to determine formula weight of compounds and then determine percent mass composition for each element in the compound.

• You will learn how to use empirical formula and percent mass composition to determine if substance is pure.

Closing Task:

You can take a quiz to determine how you are learning how to name and write formulas for a variety of substances.
