Challenge Problems

Push your limits with challenges.

Question 1

Using the Law of Multiple Proportions, calculate the ratios of mass for a compound where 4 grams of element X combine with 12 grams of element Y to form compound A, and 4 grams of element X combine with 24 grams of element Y to form compound B. Simplify both ratios.

๐Ÿ’ก Hint: Look for how the same mass of X compares in different compounds to Y.

Question 2

How does the Law of Multiple Proportions apply in determining the empirical formula of a compound formed by elements A and B when 2g of A combines with 8g of B in one compound and in another compound, 2g of A combines with 16g of B?

๐Ÿ’ก Hint: Think about how mass ratios provide the empirical formula!
