Answer:
[tex]N=9.033\times 10^{22}\ \text{units}[/tex]
Explanation:
It is given that,
Number of moles, n = 0.15
We need to find the number of particles in 0.15 mol of NaCl. Let N are the number of particles i.e.
Number of particles = number of moles × Avagadro's number
[tex]N=n\times N_A[/tex]
So,
[tex]N=0.15\times 6.022\times 10^{23}\\\\N=9.033\times 10^{22}\ \text{units}[/tex]
So, the number of particles are [tex]9.033\times 10^{22}\ \text{units}[/tex].
