Consider the hypothetical elements A, B, and C and assume these elements react to form several different binary covalent compounds. Two of the compounds are A2B2 and B3C. These two compounds have the same molar mass and compound B3C is 90.0% B by mass. If a binary compound between A and C is 60.0% A by mass, which of the following could be the formula for this compound? Hint: determine some relative masses for the elements.
a. A3C4
b. AC2
c. A4C2
d. A6C2
e. AC
