Density,mass, moles and multiple elements
This page presents random "word" problems in the area of elements, density, 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 need a periodic table or chart of the elements which
includes densities to do these problems. Be very careful about the atomic symbol. You must enter it exactly as
is shown on the Periodic Table.
