Suppose you dissolve a soda can that contains 14.0 g of aluminum in excess hydrochloric acid. As the can dissolves, you collect all of the H2 gas generated and divert it to inflate a balloon. The balloon expands under typical room conditions to a pressure of 1.00 bar and a temperature of 22.0°C. Assuming none of the gas escaped and that the balloon assumes a spherical shape, what would the balloon’s diameter be (in centimeters)?

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.
