The answer depends on the quantity of Xenon.
19.2 moles
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
5.66 X 1023 atoms of xenon (1 mole Xe/6.022 X 1023) = 0.940 moles of xenon ------------------------------
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
0.94 moles.
19.2 moles
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
Approx 0.46 moles.
5.66 X 1023 atoms of xenon (1 mole Xe/6.022 X 1023) = 0.940 moles of xenon ------------------------------
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
0.94 moles.
There are 5816 grams.
The answer depends on the quantity of XeF6
mass (in grams) = number of moles x molecular weight. So for 0.015 moles of XeF4, the mass = 0.015 x 207.284 = 3.11 g
3.2 mol XeF_7 * 7mol F/1mol XeF_7 = 22.4 mol F Easy as pie.
Convert all to moles: 0.584g Xe = 0.0044mol. 86.4g Ar = 2.16mol. 3.62g Ne = 0.18 mol. Total moles = 0.0044 + 2.16 + 0.18 = 2.34mol. Mole fraction = moles of 1 component divided by total moles of all components, so 0.0044/2.34 = 0.0019.
