The student realized that they did not dissolve all of the magnesium in the reaction and had to redo the trial. The student then redid the calculations in Question #10 with the new data and found the pressure of hydrogen gas to be 712.6 mm Hg. If they generated 39.54 mL of hydrogen gas at 23.00oC, what is the corresponding volume (in mL) at STP? Report your answer to FOUR sig figs.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
