SOMEONE PLEASE HELP ME! provide explanations please

hope this document helps! it's kinda hard to type out the explanation but ill try

Explanation:

divide the percenatge by the molar mass of the element.

(do this for both elements) \

find the lowest number and divide the results with it

now you have your empirical formula (with the rounded answers)

then find the molar mass of your empirical formula

divide the number given (267) by the molar mass to get a rounded number.

multiply that rounded answer to your empirical formula to get your empirical formula. :)

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
