The empirical mass of C\(_6\)H\(_{12}\)O\(_6\) is
[H =1, C = 12, O = 16]
90
180
45
30
Explicação
Firstly, determine the empirical formula.
Molecular formula for the compound : C\(_6\)H\(_{12}\)O\(_6\)
To find the empirical formula, the subscripts of each element must be divided by their greatest common divisor, which is 6.
C\(_6\)H\(_{12}\)O\(_6\) → CH\(_2\)O
Empirical formula : CH\(_2\)O
Now, we can calculate the empirical mass of CH\(_2\)O = 12 + (1 x 2) + 16
= 30.
