Question

Please help. What is the empirical formula mass for C4H12O4?

Answer 1

61g/mol

Explanation:

The empirical formula of compound is its simplest formula. It shows the simplest ratio by which the atoms are combined.

  In the formula   C₄H₁₀O₄

 we have:

        4 moles of carbon     10 moles of hydrogen    4 moles of Oxygen;

                 4 : 10 : 4

The simplest ratio can be obtained by dividing through by the highest common factor which is 2;

              4/2   10/2    4/2

               2       5        2

the empirical formula is C₂H₅O₂

The formula mass is the sum of the atomic weights;

   C₂H₅O₂ = (2 x 12) + (5x1) + (2x 16) = 24 + 5 + 32 = 61g/mol
