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

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

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
