Question

6.02 X 10 to the 24th molecules of CuF is equal to how many moles of CuF?

Answer 1

9.9 moles of CuF

Step-by-step 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
