Answer:
N2H4
Explanation:
Find the mass of the empirical formula, which is 16.03
Take the formula mass and divide it by the empirical mass.
This should give you an answer of 2 (well, 1.99 but it is close enough to a whole number to where you can just use 2).
Multiply the subscripts of NH2.
N has a subscript of 1, so now it will have a subscript of 2.
H has a subscript of 2, so it will now have a subscript of 4.
Therefore, your answer is N2H4.
