Moles needed to react completely?
« on: October 06, 2010, 03:42:22 PM »
Hi, How many moles of H2SO4 react completely with 1 mole of Na2CO3?

Is it                             98g                                     :                                                106
                                      x                                    :                                                  1


=answer =          0.92mol ?

Start with the reaction equation.

H2SO4+ Na2CO3 --> Na2SO4 + CO2 + H2O

Ok now what?
