Answer:
4.52 x 10²⁴ atoms Cl
Step-by-step explanation:
A mole is a name that means a certain number like a dozen means 12. 1 mole of chlorine atoms is 6.022 x 10²³ chlorine atoms. The unit conversion is 6.022 x 10²³/mol.
![7.50molCl*(6.022 x 10^(23) atomsCl)/(1molCl) = 4.5165*10^(24) atomsCl](https://img.qammunity.org/2021/formulas/chemistry/high-school/og3y1eb6onmymmbhv0q0pd78f6ldwreuxp.png)
Round to 4.52 x 10²⁴ atoms Cl for the correct number significant figures.
