A 2.241 g sample of nickel reacts with oxygen to form 2.852 g of the metal oxide. Calculate the empirical formula of the oxide.
Give the number of moles of each element to support you answer.

YOU can figure the moles of oxygen, and Ni.
now, get the mole ratio: MolesNi/molesO
(ie, divide both moles by the lowest number).
The formula will be NinOm</sub)
where n/m= mole ratio above. If it is a weird number, such as .33, get it to
.33/1=n/m multiply by 3, so that n/m =1/3 In this case it should be weird.

It shouldn't be weird, it should be a simple whole number.

Doesn't that look like 1:1. It does to me.
