Answer:
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
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 [tex]XeF_4[/tex]
First of all, we would calculate the number of moles of [tex]XeF_4[/tex].
[tex]Number\;of\;moles = \frac{mass}{molar\;mass}\\\\Number\;of\;moles = \frac{4.658}{207.28}[/tex]
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:
[tex]Mass = molar\;mass \times number\;of\;moles[/tex]
Substituting the given parameters into the formula, we have;
[tex]Mass = 0.0225 \times 131.29[/tex]
Mass = 2.954 grams
