Answer:
54.26 × 10²³ representative particles
Explanation:
Given data:
Number of moles of water = 9.01 mol
Number of representative particle = ?
Solution:
one mole of any substance contain 6.022 ×10²³ representative particles.
9.01 mol × 6.022 ×10²³ representative particles
54.26 ×10²³ representative particles
The number 6.022 × 10²³ is called Avogadro number.
"It is the number of atoms , ions , molecules or representative particles in one gram atom of element, one gram molecules of compound and one gram ions of a substance "
