Express your answer to three significant figures. This balanced equation shows the reaction of sodium hydroxide and sulfuric acid:
2NaOH + H2SO4 - Na2SO4 + 2H20.
In a laboratory experiment, a student mixes 355 grams of sulfuric acid with an excess of sodium hydroxide. What is the theoretical mass of
sodium sulfate produced? Refer to the periodic table and the polyatomic ion resource.
The theoretical mass of sodium sulfate is
grams.

The theoretical mass of is, 514 grams.

Explanation : Given,

Mass of = 355 g

Molar mass of = 98 g/mol

First we have to calculate the moles of .

Now we have to calculate the moles of

The balanced chemical equation is:

From the reaction, we conclude that

As, 1 mole of react to give 1 mole of

So, 3.62 mole of react to give 3.62 mole of

Now we have to calculate the mass of

Molar mass of = 142 g/mole

Therefore, the theoretical mass of is, 514 grams.
