Calculate the number of grams of xenon in 3.566 g of the compound xenon tetrafluoride.
3.566 XeF4 x (atomic mass Xe/molar mass XeF4) = g Xe
To calculate the number of grams of xenon in a compound, we need to determine the molar mass of xenon tetrafluoride (XeF4).
The molar mass of xenon (Xe) is 131.293 g/mol, and the molar mass of fluorine (F) is 18.998 g/mol.
To determine the molar mass of xenon tetrafluoride, we multiply the molar mass of xenon by its subscript (1) and the molar mass of fluorine by its subscript (4), and then add them together:
Molar mass of XeF4 = (molar mass of Xe) + (4 x molar mass of F)
Molar mass of XeF4 = (131.293 g/mol) + (4 x 18.998 g/mol)
Molar mass of XeF4 = 207.293 g/mol
Now, we can calculate the number of moles of xenon tetrafluoride using the given mass and molar mass:
Number of moles of XeF4 = Mass of XeF4 / Molar mass of XeF4
Number of moles of XeF4 = 3.566 g / 207.293 g/mol
Number of moles of XeF4 ≈ 0.0172 mol
Since xenon tetrafluoride has a 1:1 molar ratio of xenon to xenon tetrafluoride, the number of moles of xenon is also approximately 0.0172 mol.
Finally, we can calculate the grams of xenon by multiplying the number of moles of xenon by its molar mass:
Grams of xenon = Number of moles of xenon x Molar mass of xenon
Grams of xenon = 0.0172 mol x 131.293 g/mol
Grams of xenon ≈ 2.258 g
Therefore, there are approximately 2.258 grams of xenon in 3.566 g of xenon tetrafluoride.
To calculate the number of grams of xenon in 3.566 g of xenon tetrafluoride, you need to first determine the molar mass of xenon tetrafluoride.
Xenon tetrafluoride (XeF4) consists of one xenon atom and four fluorine atoms. The molar mass of xenon is 131.29 g/mol, and the molar mass of fluorine is 18.998 g/mol.
To calculate the molar mass of xenon tetrafluoride, you multiply the molar mass of each atom by the number of atoms present, then add them together:
Molar mass of xenon tetrafluoride = (1 * molar mass of xenon) + (4 * molar mass of fluorine)
Molar mass of xenon tetrafluoride = (1 * 131.29) + (4 * 18.998)
Molar mass of xenon tetrafluoride = 131.29 + 75.992
Molar mass of xenon tetrafluoride = 207.282 g/mol
Now that we have the molar mass of xenon tetrafluoride, we can calculate the number of moles of xenon in 3.566 g of the compound:
Number of moles of xenon = Mass of xenon tetrafluoride / Molar mass of xenon tetrafluoride
Number of moles of xenon = 3.566 g / 207.282 g/mol
Calculating this value gives us the number of moles of xenon. However, we need to convert this to grams:
Number of grams of xenon = Number of moles of xenon * Molar mass of xenon
Number of grams of xenon = (3.566 g / 207.282 g/mol) * 131.29 g/mol
Simplifying this calculation will give you the number of grams of xenon in 3.566 g of xenon tetrafluoride.
