How many grams do 1.80x10^24 molecules of UF6 weigh?

Mass = 1056.06 g

Explanation:

Given dа ta:

Mass of UF₆ = ?

Molecules of UF₆ = 1.80*10²⁴

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 * 10²³ is called Avogadro number.

For example,

1 mole of UF₆ = 6.022 * 10²³ molecules of UF₆

1.80*10²⁴ molecules / 6.022 * 10²³ molecules * 1 mol

3 mole UF₆

Mass of UF₆:

Mass = number of moles * molar mass

Mass = 3 mole * 352.02 g/mol

Mass = 1056.06 g
