Calculate the number of moles for 3.34x1024 formula units of copper (II) hydroxide (Cu(OH)2).

The number of moles is 5.54

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023 * 10²³ particles per mole. Avogadro's number applies to any substance.

Then the following rule of three can be applied: if 6.023 * 10²³ formula units are contained in one mole, 3.34*10²⁴ formula units in how many moles will they be?

moles= 5.54

The number of moles is 5.54
