This is a basic exercise in the use of molar volumes of the elements. You might
need a table of element densities to complete this exercise. When you press "New Problem" a question will appear. Determine the value of the answer, enter it in the answer cell and press "Check Answer"; results and scoring will appear in the table. Pressing "Show Answer" will cause the correct answer to appear and you will no longer be able submit an answer for that problem. In the solution "MV" is used as the symbol for molar volume. Pressing "Show Molar Volume" will display a table with volumes per mole of the element (cm3/mol).
