If the molar mass of a compound is 78. 12 g and the empirical formula is ch, what is the value of the integer that relates the empirical formula to the molecular formula?.

Respuesta :

rspill6

Answer:

C6H6

Explanation:

The empirical formula, CH, has a unit mass of 13 (12+1).  78/13 = 6

There are 6 units of CH in the intact compound.  The molecular formula must be C6H6.

C:  6 * 12 = 72

H:  6 * 1 =     6

Total     =    78
