Word Problems - Elements and Moles
This page presents random "word" problems in the area of elements, mass and moles.
When you press "New Question", a question will appear in the top frame. Calculate the
answer and enter it in the cell. Then, press "Check Answer" and the results appear in the
table. If you get a problem wrong, you should redo it until you get it correct, but you
can press "New Question" at any time. You will need a periodic table or chart of the elements
to do these problems. Be very careful about the atomic symbol. You must enter it exactly as
is shown on the Periodic Table.
