In an experiment, it was found that 11.775 g of Sn combined with 3.180 g of O. Write the empirical formula for the compound that is formed.

The empirical formula for the given compound is

Explanation:

Mass of Sn = 11.775 g

Mass of O = 3.180 g

To formulate the empirical formula, we need to follow some steps:

Step 1: Converting the given masses into moles.

Moles of Sn =

Moles of O =

Step 2: Calculating the mole ratio of the given elements.

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.0992 moles.

For Sn =

For O =

Step 3: Taking the mole ratio as their subscripts.

The ratio of Sn : O = 1 : 2

Hence, the empirical formula for the given compound is

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
