Question

How many moles of H2SO4 are need to produce 13 moles of H2O?

I don´t understand anything about this unit

Answer 1

Assuming you're talking about neutralization, 13 moles.

Explanation:

It depends on the reaction(s) the sulphuric acid `H_2SO_4` is undergoing, assuming we're neutralizing it with some base, like say, `Ca(OH)_2` we have the following equation:

`H_2SO_4 + Ca(OH)_2 \rarr CaSO_4 + H_2O`

We can then see that if we want 13 moles of water, we need 13 moles of sulphuric acid.
