1mole of hydrogen will gives 22.4lit
X moles of hydrogen will gives 0.448lit
Weight of hydrogen = 0.448 liters
Number of moles of hydrogen in 0.448 liter of hydrogen gas at STP.
Let the number of moles of hydrogen in 0.448 liter of hydrogen gas at STP be 'X'.
At STP, 1 mole of all gas weighs 22.4 liters. Thus it can be expressed as
1 mole of hydrogen gas = 22.4 liters
∴ X mole of hydrogen gas = 0.448 liters
When the above given equations are cross multiplied, it gives
X × 22.4 = 1 × 0.448
X = 0.02
Number of moles of hydrogen in 0.448litre of hydrogen gas at STP is calculated as 0.02 moles.

the presence of water in mining sites create a range of operational and stability problems and requires drainage to avoid slope stability problems and action to minimize oxidation of metallic sulfides and corrosion of mining and equipment. the quality of the mine water depends on a series of geological, hydrological and mining conditions, vary significantly from mine to mine . mining by its nature consumes as well as diverts water and can also pollute water resources of corresponding author.
