Question

Explain the terms percentage
composition, empirical formula and molecular formula.
​

Answer 1

Explanation:

percent composition is the term used to describe the percent by mass of each element in a compound. ... Molecular formulas tell you how many atoms of each element are in a compound. empirical formulas tell you the simplest or most reduced ratio of elements in a compound.

Answer 2

Answer:

• Percentage Composition:- Mass% of an element=

      =  $\frac{Mass of that element in the compound}{Molar mass of the compound } * 100$

• Empirical formula= Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.
• Molecular formula = A molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. The empirical formula represents the simplest whole-integer ratio of atoms in a compound.
