The rapid depletion of fossil fuels has inspired extensive research in the area of alternative and renewale energy sources. Of these, hydroden is the most Contemplated fuel of the future . Howevercost effective production and hazard free storage are major issuses is using `H_(2)` (Note : use the data in table-1 given at the end of partA, whenever necessary.)
A cylinder contains hydrogen at a pressure of 80Moa at `25^(@)C` , Assuming ideal behaviour , Calculate the density of hydrogen in the cylinder in `Kg//m^(3)` .

Answer

`p=64.58 kg m_(-3)`
