Determine the empirical formula for c6n4o10
ANEK [815]
<h2>Let us derive empirical formula </h2>

Explanation:

We are given with compound C₆N₄O₁₀: mass percentage of all is :

For C = 12 x 6 /288=0.25%

For N= 14 x 4 /288=0.19%

For 0= 16 x 10/288=0.5%

The elements present are :

         Atomic mass   moles                       Simplest ratio           rounding off

C      12                        0.25/12=0.020             0.02/0.02=1           2

N       14                       0.9/14=0.06                    0.06/0.02=3         6

O       16                        0.5/16=0.03                   0.03/0.02=1.5       3

The empirical formula derived is : C₂n₆O₃

What's is the difference between relative abundance vs percent abundance
guajiro [1.7K]
Relative means you take the required amount from the actual amount which gives you the excess or abundance, its relative because you compare it to the required amount.
The percent abundance is the relative abundance as a percentage of the required amount.
Therefore % abundance= (abundance/required amount) X 100

The key difference is that percentages are standardised as a number out of 100 which allows you to compare them with other percentages without any calculations.

Hope that helps.
