72g H2O x 1 mol H2O/18.02g H2O = 3.99 mol H2O
Answer:
Multiply 3 by Avogadro's number.
Explanation:
The mole can be defined as the amount of a substance that contains Avogadro’s number of particles, 6.02 x 10²³.
For elementary particles:
Number of particles=
number of moles x 6.02 x10²³
From the question,
Number of moles = 3moles
Number of particles = 3 x 6.02 x10²³
