Calculate the number of grams of xenon in 4.658 g of the compound xenon tetrafluoride.

The number of grams of xenon in 4.658 grams of the compound xenon tetrafluoride is 2.954 grams.

Given the following data:

To determine the number of grams of xenon in 4.658 grams of the compound xenon tetrafluoride:

The chemical formula for xenon tetrafluoride is

First of all, we would calculate the number of moles of .

Number of moles = 0.0225 mole

By stoichiometry:

1 mole of xenon tetrafluoride = 1 mole of xenon

0.0225 mole of xenon tetrafluoride = 0.0225 mole of xenon

To find the mass of xenon:

Substituting the given parameters into the formula, we have;

Mass = 2.954 grams

The mass of xenon in the compound is 2.950 grams

Explanation:

Step 1: Data given

Mass of XeF4 = 4.658 grams

Molar mass of XeF4 = 207.28 g/mol

Step 2: Calculate moles of XeF4

Moles XeF4 = mass XeF4 / molar mass XeF4

Moles XeF4 = 4.658 grams / 207.28 g/mol

Moles XeF4 = 0.02247 moles

Step 3: Calculate moles of xenon

XeF4 → Xe + 4F-

For 1 mol xenon tetrafluoride, we have 1 mol of xenon

For 0.02247 moles XeF4 we have 0.02247 moles Xe

Step 4: Calculate mass of xenon

Mass xenon = moles xenon * molar mass xenon

Mass xenon = 0.02247 moles * 131.29 g/mol

Mass xenon = 2.950 grams

The mass of xenon in the compound is 2.950 grams

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.
