The chloride of a solid metallic element contains 57.89% by mass of the element. The specific heat of the element is 0.0324 cal `"deg"^(-1)g^(-1)`. Calculate the exact atomic mass of the element.

Explanation

Equivalent mass of the element `=(6.4)/(42.11)xx35.5=48.8`
Approximate atomic mass `=(6.4)/(0.0324)=200`
Valency `=(200)/(48.8)=4`
Exact atomic mass `=48.8xx4=195.2`
