Question

Encontrar la fórmula molecular tomando en cuenta que la fórmula mínima es CH2 y el peso molecular es 42g.

Answer 1

Mm Fórmula  empirica
C: 1  x 12 = 12 g/mol
H: 2  x 1  = 2 g/mol
``````````````````````````````
           Mm = 14 g/mol

n = 42 g/ 14 g/mol

n = 3

FM = (FE)n

FM = (CH2)3  = C3H6
