How to find the mass of hydrogen produced if volume temperature and pressure known
Answers
Hydrogen gas has the chemical formula H2 and the molecular weight of 2. This gas is the lightest substance among all chemical compounds and the most abundant element in the universe. Hydrogen gas has also drawn significant attention as a potential energy source. Hydrogen can be obtained, for example, by electrolysis of the water. You calculate the amount of hydrogen in moles either from the gas mass or using the ideal gas law.
Familiarize yourself with the ideal gas law that is given as PV = nRT; where "P" represents pressure, "V" is volume, "n" is the number of moles of a gas and "T" is temperature. "R" stands for the molar gas constant, which is 8.314472. The gas constant lets you work with the standard units of Kelvins for temperature, moles of gas amount, pressure in pascals and volume in cubic meters.
Add the value 273.15 to the temperature in Celsius (C) to convert it to Kelvin (K).
