E2d. On birthday parties, balloons are commonly used. You can buy the inflated balloons or buy a helium tank and inflate by yourself. The helium tank has a cylindrical shape. The height is 18.13 inch and the diameter is 12.5 inch. Please estimate the number of balloons that can be inflated with the He gas in the tank by answering the following questions step by step. The outside pressure is 1.00 atm. 1 inch = 2.54 cm, .   (d) The pressure inside the tank was 8.68 atm. How many 9-in balloons can we inflate? Assume that the temperatures are the same for both the balloon and the tank.

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.
