Answer 1

Answer:

Hello

Explanation:

Your answer is .0071302902761.

Answer 2

To calculate the number of moles of Uranium hexafluoride can be taken by dividing the given mass of the substance by the molar mass of the substance.

Number of Moles= Given mass / Molar mass

Here,

Given mass= 2.51 g

Molar mass of UF6= 352.02 $gmol^{-1}$

         = 2.51/352.02

         = 0.00713027668.

There are 0.00713027668 molecules in 2.51 grams of UF6.
