H2SO4+2NaOH->2H2O+Na2SO4

Question

1.) How many grams of H2SO4 are needed to produce 135L of water?

2.) How many molecules of water are produced when 12g of sodium sulfate are created?

Answer 1

how many moles of H2O in 135L (at 18g/mole)?
half that many moles of H2SO4

Now use Avogadro's Number to find # molecules.

Answer 2

So is this right?

1.) 18g H2SO4. If so why wouldn’t we include Sulfur?

2.) 108x6.02^23= 108molecules H2O

Thanks for the help.
