Answer
The chemical formula for this acid is $HNO_3$
Work Step by Step
A hydrogen atom has 1 proton and a mass of 1 u. We can find the number of hydrogen atoms in this molecule:
$(0.016)(63~u) = 1.0~u$
The molecule has one hydrogen atom.
A nitrogen atom has 7 protons and 7 neutrons. It has a mass of 14 u. We can find the number of nitrogen atoms in this molecule:
$(0.222)(63~u) = 14.0~u$
The molecule has one nitrogen atom.
An oxygen atom has 8 protons and 8 neutrons. It has a mass of 16 u. We can find the number of oxygen atoms in this molecule:
$(0.762)(63~u) = 48.0~u$
The molecule has three oxygen atoms.
The chemical formula for this acid is $HNO_3$
