How many molecules of water can be made from 9.21 x 10^22 molecules of hydrogen sulfate?
The equation is 2Fe(OH)3 + 3H2SO4 -> Fe2(SO4)3 + 6H2O
To find the number of molecules of water that can be made from a given number of molecules of hydrogen sulfate, we need to use the stoichiometry of the balanced chemical equation.
According to the balanced equation:
2Fe(OH)3 + 3H2SO4 -> Fe2(SO4)3 + 6H2O
We can see that 3 moles of H2SO4 react to produce 6 moles of H2O. This means that for every 3 molecules of H2SO4, 6 molecules of water are produced.
So, for every 3 molecules of H2SO4:
6 molecules of H2O are produced
Now, we need to calculate how many molecules of water can be produced from 9.21 x 10^22 molecules of H2SO4.
First, we find the moles of H2SO4:
Moles of H2SO4 = Number of molecules of H2SO4 / Avogadro's number
Avogadro's number is approximately 6.022 x 10^23 molecules/mol.
Moles of H2SO4 = (9.21 x 10^22) / (6.022 x 10^23)
Next, we use the stoichiometry from the balanced equation to find the moles of H2O produced:
Moles of H2O = Moles of H2SO4 x (6 moles H2O / 3 moles H2SO4)
Finally, we convert moles of H2O back to the number of molecules of H2O:
Number of molecules of H2O = Moles of H2O x Avogadro's number
By following these steps, you can calculate the number of molecules of water that can be made from a given number of molecules of hydrogen sulfate.
