what is the empirical formula of aspirin, C9H8O4? is it the same again ?
Exactly what do you mean by "Is it the same again?" If you mean is it C9H8O4, yes.
To determine the empirical formula of a compound, you need to find the simplest whole number ratio of the atoms present in the compound. In the case of aspirin, whose molecular formula is C9H8O4, the empirical formula can be obtained by dividing all the subscripts by their greatest common divisor (GCD).
Step 1: Find the GCD of the subscripts.
In this case, the GCD of 9, 8, and 4 is 1.
Step 2: Divide all the subscripts by the GCD.
The empirical formula of aspirin is found by dividing C9H8O4 by 1, which results in C9H8O4 itself.
Therefore, the empirical formula of aspirin is C9H8O4.
To find the empirical formula of a compound, you need to determine the simplest whole number ratio of atoms present in the compound. The molecular formula of aspirin is C9H8O4, but this does not represent the empirical formula.
To determine the empirical formula, we need to find the greatest common divisor (GCD) of the subscripts.
In this case, the GCD of 9, 8, and 4 is 1. To simplify the formula, we divide each subscript by 1:
C9 ÷ 1 = C9
H8 ÷ 1 = H8
O4 ÷ 1 = O4
So, the empirical formula of aspirin remains the same: C9H8O4.
