Question

The empirical formula for a compound is CH2. If n is a whole number, which shows a correct relationship between the molecular formula and the emperical formula.

Answer 1

Answer:

D)subscript of C in molecular formula = n x subscript of C in empirical formula

Explanation:

THIS IS THE COMPLETE QUESTION BELOW;

.The empirical formula for a compound is CH2. If n is a whole number, which shows a correct relationship between the molecular formula and the empirical formula? a)

empirical formula mass / molecular mass = n

B) molecular mass = element mass / empirical formula mass ´ 100

c) subscript of H in empirical formula = 2  subscript of H in molecular formula

D) subscript of C in molecular formula = n  subscript of C in empirical formula

An empirical formula can be regarded as "shorten form" of a molecular formula. Instance of this is

A compounds CH4, C2H8, C4H12... with empirical formula of CH4. In this case a constant "n" represent the difference that exist between empirical formula and molecular formula, "n" which is a whole number, molecular formula is the numerator.

Therefore, subscript of C in molecular formula = n x subscript of C in empirical formula
