Background

The formula of a chemical compound is really a very compact code for the percent composition of the compound. Using the formula of a compound, the mass of the compound containing a given mass of an element can be calculated. Textbook Discussion: Section 5.8, page 123. See Also: Example X, page 126 and problem 44, page 150.

Problem

In theory, the compound  Be₄O(C₃H₅O₂)₆ can be chemically decomposed so that all of the beryllium  in the compound is isolated. What mass of this compound would need to be decomposed to produce 66.1 grams of beryllium? Atomic Masses: Be=9.01 O=16.0 C=12.0 H=1.00 amu
