Calculate the number of molecules in 6.7 moles of alcl3

According to the Avogadro’s law I mole of any substance contains = 6.023 x 1023

Number of molecules in one mole= 6.023 x 1023

Therefore number of molecules in 6.7 moles of AlCl3:

6.023x1023 molecules /1.0 mole * 6.7 mole

= 40.3541 x 1023 molecules

= 4.03541 x 1024 molecules

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
