Answer:
Mass = 1056.06 g
Explanation:
Given data:
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
