Calculate the percent composition of each of these known
compounds.
5. Carvone (responsible for the smell in caraway
seeds) C10H14O
6.Sodium
tartrate Na2C4H4O6
7. Calcium Hydrogen Oxalate
Ca(HC2O4)2
8. Ammonium phosphate
(NH4)3PO4
Using the results from problems 5-8, calculate the amount of
hydrogen, in grams, in the following amounts of these
compounds.
Hint: Multiply the percentage of Hydrogen in each
substance by the number of grams given. For example, if the
percent of hydrogen in #5 was 25% (just using this as an example)
multiply 350 x 25/100 to get the number of grams of hydrogen in
#9.
9. 350 g C10H14O
10. 20.2
g Na2C4H4O6
11.124
g Ca(HC2O4)2
12. 378
g (NH4)3PO4
Which of the following compounds has the highest percentage of
iron content?
13.
Fe2O3, Fe(OH)3 or Fe(C2H3O2)2
Calculate the percent composition of each of these known
compounds.
14. Na2O2
15. H2S
16. C16H26O4N2S
17. Mg(OH)2
Solve the followng Problems.
18. How many grams of oxygen can be produced from the
composition of 137g of Ca(OH)2?
19. How much iron, in grams, can be recovered from
52.0g of Fe2O3?
20. How much silver, in grams, can be produced from 521g of
Ag2S?
