This calculator can be used as common scientific calculator (sin, cos, log, power, root, memory), but it also includes a molecular weight calculator and the tables with various physical and chemical constants. The calculator contains a list with task history, storing all the recent inputs and results.

The purpose of this experiment is to calculate the percentage composition of a compound and from this determine the relative atomic weight of the unknown element in the compound. Since this is a quantitative experiment, all measurements recorded in your data table to the proper number of significant digits.
