Answer 1

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.
