What is the theoretical value and yield for Sulphuric Acid and Calcium Carbonate?

Question

Experiment was different concentrations of 0.5, 0.4, 0.3 concentrations of sulphuric acid reacted with calcium carbonate (1.027g). The loss of mass was calculated.

Answer 1

The question as posed is incomplete. We will need additional information to answer this properly.

First, what are your units of concentration for sulfuric acid? You give them as 0.5, 0.4 and 0.3. Is that (M), molar? Did you weight the final product (CaSO₄)? If so, what was that mass? What volume of sulfuric acid solutions did you use?

Sulfuric acid = H₂SO₄

calcium carbonate = CaCO₃

Reaction: H₂SO₄ + CaCO₃ ==> CaSO₄ + CO₂ + H₂O

We need to know volume of H2SO4, molar concentration of H2SO4 and mass of product in order to calculate theoretical and percent yield.
