Question

1. How many moles are in 3.01 x 10^23 molecules of Boron trichloride

Answer 1

Answer: There are 0.499 moles present in
`3.01 * 10^(23)` molecules of Boron trichloride.

Step-by-step explanation:

According to mole concept, there are
`6.022 * 10^(23)` molecules present in 1 mole of a substance.

Hence, number of moles present in
`3.01 * 10^(23)` molecules are as follows.

`Moles = (3.01 * 10^(23))/(6.022 * 10^(23))\\= 0.499 mol`

Thus, we can conclude that there are 0.499 moles present in
`3.01 * 10^(23)` molecules of Boron trichloride.
