Answer:
4.9 x 10²²hockey pucks
Explanation:
Given parameters:
Number of moles of hockey = 0.0814moles
Unknown:
Number of pucks there = ?
Solution:
A mole of a substance is made up of Avogadro's number of particles.
Therefore;
1 mole of hockey pucks will contain 6.02 x 10²³ hockey pucks
0.0814 mole of hockey pucks will contain :
0.0814 x 6.02 x 10²³ = 4.9 x 10²²hockey pucks
