Answer:

N2H4

Step-by-step explanation:

  1. Find the mass of the empirical formula, which is 16.03
  2. Take the formula mass and divide it by the empirical mass.
  3. 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).
  4. Multiply the subscripts of NH2.
  5. N has a subscript of 1, so now it will have a subscript of 2.
  6. H has a subscript of 2, so it will now have a subscript of 4.
  7. Therefore, your answer is N2H4.
