Answer:
![N=9.033* 10^(22)\ \text{units}](https://img.qammunity.org/2021/formulas/chemistry/college/ve0e5h1fpodxa5gc7k3qcmcvyc3my95xn4.png)
Step-by-step 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
![N=n* N_A](https://img.qammunity.org/2021/formulas/chemistry/college/y3th1r3gj3t2wyovyzlkurm601c3hoom1r.png)
So,
![N=0.15* 6.022* 10^(23)\\\\N=9.033* 10^(22)\ \text{units}](https://img.qammunity.org/2021/formulas/chemistry/college/dblmptojhxfamk5c2fi39px3vgjloaf126.png)
So, the number of particles are
