Answer:
9.9 moles of CuF
Explanation:
Given data:
Number of molecules of CuF = 6.02×10²⁴
Number of moles of CuF = ?
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,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
For CuF:
6.02×10²⁴ molecules× 1 mol / 6.022 × 10²³ molecules
0.99 ×10¹ mol
9.9 moles of CuF
