8.67 x 1018 atoms Zn calculate the number of representative particles or moles for each of the following

Multiply the no. of moles with Avogadro's constant which is 6.02*10^23

the mole ratio of Zinc * Avogadro's constant *8.67*1018

this should help you get what you want

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
