Question

Hydrogen fluoride is produced from the reaction of calicum fluoride with sulfuric acid, which also forms calicum sulfate. 6.00 kg of calicum fluoride are reacted with an excess of sulfuric acid. How much hyrdogen fluoride is formed if the percent yield is 93.0%?

Answer 1

Here is an example. Just follow the steps. http://www.jiskha.com/science/chemistry/stoichiometry.html

Multiply the theoretical yield you find by 0.93.

Answer 2

is the theoretical yield 6.00?

Answer 3

No. Where did you get the 6.00? From the problem of 6.00 kg? You must go through the procedure outlined in the link to find the theoretical yield.
