The number of moles of nitrogen atoms are there in 1.64 x 1023 molecules of dinitrogen trichloride is 0.544.
What are a number of moles?
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
1 mole is 6.022 × 10²³
[tex]1\; molecule = \dfrac{1}{6.023 \times 10^2^3}[/tex]
The given number of moles are 1.64 x 10²³
[tex]1.64 \times 10^2^3= \dfrac{1}{6.023 \times 10^2^3} = 0.272 \\[/tex]
Now, there are two molecules of nitrogen in the dinitrogen trichloride
So, 0.272 x 2 = 0.544
Thus, the number of moles of nitrogen atoms are there in 1.64 x 1023 molecules of dinitrogen trichloride is 0.544.
