A2.241-g sample of nickel reacts with oxygen to form 2.852 g of the metal oxide.
calculate the empirical formula for oxide.

The empirical formula is =

Explanation:

Given that:- Mass of nickel = 2.241 g

Mass of the oxide formed = 2.852 g

Mass of the oxygen reacted = Mass of the oxide formed - Mass of nickel  = 2.852 g - 2.241 g = 0.611 g

Molar mass of nickel  = 58.6934 g/mol

Moles of nickel = = 0.03818 mol

Molar mass of oxygen  = 15.999 g/mol

Moles of nickel = = 0.03818 mol

Taking the simplest ratio for Ni and O as:

0.03818 : 0.03818 = 1 : 1

The empirical formula is =
