For the following reaction, 3.81 grams of sulfuric acid are mixed with excess barium hydroxide. The reaction yields 8.45 grams of barium sulfate.

barium hydroxide (aq) + sulfuric acid (aq) ---> barium sulfate (s) + water (l)

This is an incomplete question, here is a complete question.

For the following reaction, 3.81 grams of sulfuric acid are mixed with excess barium hydroxide. The reaction yields 8.45 grams of barium sulfate.

What the is theoretical mass of barium sulfate?

The theoretical mass of is, 9.08 grams.

Explanation : Given,

Mass of = 3.81 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, 0.0389 mole of react to give 0.0389 mole of

Now we have to calculate the mass of

Molar mass of = 233.38 g/mole

Therefore, the theoretical mass of is, 9.08 grams.

im pretty sure its b
