50g of H2SO4 produce how many grams of H2?
you would do a conversion factor.
50g of H2SO4 x 1mol sulfuric acid/ molar mass of sulfuric acid x grams of H2/ 1mol H2
You get grams of H2.
Get it?
To determine how many grams of H2 are produced from 50g of H2SO4, we need to use the balanced chemical equation for the reaction.
The balanced chemical equation for the reaction of H2SO4 with H2 is:
H2SO4 + H2 → H2S + 2H2O
From the equation, we can see that 1 mole of H2SO4 reacts with 1 mole of H2 to produce 2 moles of H2.
To calculate the moles of H2SO4 given its mass, we need to know the molar mass of H2SO4 which is 98.09 g/mol.
Moles of H2SO4 = Mass of H2SO4 / Molar mass of H2SO4
Moles of H2SO4 = 50g / 98.09 g/mol
Now, since the mole ratio between H2SO4 and H2 is 1:1, the moles of H2 are also equal to 50g / 98.09 g/mol.
To convert moles of H2 to grams, we need to know the molar mass of H2, which is 2.02 g/mol.
Mass of H2 = Moles of H2 x Molar mass of H2
Mass of H2 = (50g / 98.09 g/mol) x 2.02 g/mol
Finally, we can calculate the mass of H2 produced from 50g of H2SO4:
Mass of H2 = (50g / 98.09 g/mol) x 2.02 g/mol
By plugging these values into a calculator, we find that approximately 1.03 grams of H2 are produced from 50 grams of H2SO4.
