using equation: 2Fe(OH)3 + 3H2SO4 -> Fe2(SO4)3 + 6H2O

question: How many Molecules of H2O can be made from 9.21 x 10^22 molecules of H2SO4?

you get six molecules of water for each three of acid, or 2:1 ratio

what is 2*9.21E22?

To determine the number of molecules of H2O that can be made from a known quantity of H2SO4, we need to use stoichiometry, which involves balancing the equation and using the molar ratios.

First, let's start by balancing the equation:
2Fe(OH)3 + 3H2SO4 -> Fe2(SO4)3 + 6H2O

The balanced equation shows that for every 3 moles of H2SO4, 6 moles of H2O are produced. Therefore, the molar ratio is 3:6, which simplifies to 1:2.

Now we need to calculate the number of moles of H2SO4 using the provided quantity:

9.21 x 10^22 molecules of H2SO4

To convert the number of molecules to moles, we need to divide by Avogadro's number (6.022 x 10^23 molecules/mol).

Number of moles of H2SO4 = 9.21 x 10^22 molecules / 6.022 x 10^23 molecules/mol

Next, since the molar ratio between H2SO4 and H2O is 1:2, we multiply the number of moles of H2SO4 by the molar ratio to determine the number of moles of H2O.

Number of moles of H2O = Number of moles of H2SO4 x 2

Finally, we need to convert the number of moles of H2O back into the number of molecules. To do this, multiply the number of moles of H2O by Avogadro's number (6.022 x 10^23 molecules/mol).

Number of molecules of H2O = Number of moles of H2O x 6.022 x 10^23 molecules/mol

By following these steps, you can calculate the number of molecules of H2O that can be made from the given quantity of H2SO4.
