Answer: There are 0.499 moles present in [tex]3.01 \times 10^{23}[/tex] molecules of Boron trichloride.
Explanation:
According to mole concept, there are [tex]6.022 \times 10^{23}[/tex] molecules present in 1 mole of a substance.
Hence, number of moles present in [tex]3.01 \times 10^{23}[/tex] molecules are as follows.
[tex]Moles = \frac{3.01 \times 10^{23}}{6.022 \times 10^{23}}\\= 0.499 mol[/tex]
Thus, we can conclude that there are 0.499 moles present in [tex]3.01 \times 10^{23}[/tex] molecules of Boron trichloride.
