In the neutralization of sulfuric acid with sodium hydroxide, the theoretical yield from 6.9g of sulfuric acid is 10g. In a synthesis, the actual yield is 7.2g. What is the percentage yield for this synthesis?

#%"Yield"="Mass recovered"/"Mass expected"xx100%#

Explanation:

And thus for this example #%"Yield"# #=# #(7.2*g)/(10*g)xx100%#

And we don't even need a calculator.........

Most of the time, we write a stoichiometric equation, that shows the molar equivalence between reactant and product, so that we can work out the limiting reagent etc.......

#H_2SO_4(aq) + 2NaOH(aq) rarr Na_2SO_4(aq) + 2H_2O#.

At any rate, you have not really quoted starting conditions here.
