Chemistry
1 answer:
Nat2105 [25]3 years ago
5 0

Answer:

The correct option is

C) Trial 1 will have the same calculated empirical formula as trial 2.

Explanation:

The empirical formula is the formula of a chemical compound that states the simplest whole number ratio of each of the atoms included in the compound. It is obtained by dividing the mass of an element present in the compound by the element's molar mass to find the mole ratio of the elements. The obtained mole value for each element is then divided by the smallest number of moles obtained in the division.

By definition the composition and ratio of elements combined in a chemical compound is fixed, therefore trial 1 will have the same calculated empirical formula as trial 2.
