When there are 0.0814 moles of hockey pucks how many hockey pucks are there?

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

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
