What is the mass percent of hydrogen in water?
11.11% The percentage of an element in a compound is 100 times the fraction, so for water the mass percent hydrogen is 11.11% and the mass percent oxygen is 88.89%.
How do you get hydrogen from methane?
In steam-methane reforming, methane reacts with steam under 3–25 bar pressure (1 bar = 14.5 psi) in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide. Steam reforming is endothermic—that is, heat must be supplied to the process for the reaction to proceed.

What is the mass percent of hydrogen?
The percentage of an element in a compound is 100 times the fraction, so for water the mass percent hydrogen is 11.11% and the mass percent oxygen is 88.89%.
How do you calculate mass percent mass?
To find it:
- Use the formula for mass percent of solute in a solvent: mass percent = (mass of solute / mass of solution) × 100.
- Rearrange it to calculate the mass of the solution: mass of solution = (mass of solute / mass percent) × 100.
- Subtract the mass of solute from the mass of solution:

How do you find mass percent?
Mass percentage is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100%.
- Also Known As: mass percent, (w/w)%
- mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100.
- mass percent = (grams of solute / grams of solute plus solvent) x 100.
