<u>Answer:</u> The correct option is Option D.
<u>Explanation:</u>
Significant figures are defined as the figures that represent the digits of a number which carry an important contribution to the numerical value, starting with the first non-zero digit. For Example: 105.268 has 6 significant figures because every digit carry its own contribution towards the numerical value.
Whenever there is multiplication, the answer will contain the same number of significant figures as there are in the least precise numerical value.
Significant figures in 8.01 are 3 and that in 4.1 are 2.
So, the answer of these two numerical value will contain 2 significant figures.
Hence, the correct option is Option D.
Answer : The empirical formula is .
Explanation :
Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.
Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.
The given molecular formula is .
For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.
In the given formula, the valence is 1.
So, the empirical formula is .
