Concept introduction:
The atomic mass of an atom is defined as the average of the total masses of the atoms in an element. Similarly, in case of molecules, the average mass of molecules is known as molecular mass. Formula mass is the mass of the atoms present in a molecular formula.
(b)
Interpretation:
The differences between molecular formula and empirical formula are to be stated.
Concept introduction:
In a chemical compound, the proportion of atoms present in a compound is given by the empirical formula. On the other hand, molecular formula represents the exact number of atoms present in a compound.

- A binary compound of carbon and hydrogen has the following percentage composition: 85.63% carbon, 14.37% hydrogen by mass. If the molar mass of the compound is determined by experiment to be between 28 and 29 g/mol, what are the empirical and molecular formulas of the compound? Empirical formula: Molecular formula:arrow_forwardA compound contains arsenic and oxygen as the only elements. A 1.626 g sample of the compound contains 1.232 g of arsenic. From these data, after determining the percent composition, by weight, what is the calculated empirical formula for the compound?arrow_forward[Tutorial: Empirical formula] This question will walk you through the process of calculating the empirical formula of a 100.0 g sample of an unknown compound from its elemental percent compositions. This problem will be solved via the following sequence of conversions: mass % mass moles mole ratio → empirical formula. Step 2: You have calculated that in a 100.0 gram sample of the unknown compound, there are 4.76 moles of nitrogen, 2.38 moles of carbon, and 4.75 moles of hydrogen. Next, determine the simplest, whole-number ratio for each element by dividing the number of moles of each by the smallest number of moles (moles mole ratio). Which of the following represent the correct, normalized mole ratio of the elements within the sample? A) 4 C: 1H : 2 N B) 1C:2 H: 2 N moles mole ratio mass C) 1C:2 H: 1N D) 2.38 C : 4.75 H: 4.76 N E) 3 C:5 H:5 N molecular struct..pdfarrow_forward
- What are the similarities in how formula weight and molar mass are calculated? A) Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, multiplying them by how many there are in the formula, and then adding the numbers together. B) Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, multiplying them by how many there are in the formula, and then subtracting the numbers from each other. C) Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, dividing them by how many there are in the formula, and then adding the numbers together. D) Formula weight and molar mass are both calculated by taking the individual atoms mass in the formula, dividing them by how many there are in the formula, and then subtracting the numbers from each other.arrow_forwardIf an oxide of chromium is 48% oxygen by mass, what is its empirical formula?arrow_forwardIs formula mass different from molecular mass and molar mass?
