Calculate the mass of aluminium oxide which contains double the number of oxygen atoms in 192 g of oxygen gas.

648

Explanation:

what you're going to do your first is to convert the 192g to number of atoms

firstly you are going to convert 192 to moles using the formula reacting mass all over molar mass, into it that you're going to get 12 as your answer, you Dey multiply the 12 to avocados constant

in doing that you have I've gotten the number of atoms present in 192 g of oxygen

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
