Explanation:
The earth moves which makes the stars and everything in space seem like its moving
The gravitational force between the objects depends on the mass of the objects and the distance between them.
2075g of XeF₆ is present in 8.46 moles of XeF₆
<u>Explanation:</u>
Given:
XeF₆ is xenon hexafluoride
number of moles of XeF₆ is 8.46
Mass of XeF₆ present, m = ?
We know,
Molecular weight of XeF₆, M is 245.28 g/mol
and
number of moles, n = mass of XeF₆ present / molecular weight of XeF6

Therefore, 2075g of XeF₆ is present in 8.46 moles of XeF₆
