Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation: Zn(s) + 2HCI(aq)¬ZnCl2(aq) + H2(g) The product gas, H,, is collected over water at a temperature of 20 °C and a pressure of 755 mm Hg. If the wet H, gas formed occupies a volume of 6.66 L, the number of moles of Zn reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.

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.
