My chemistry teacher gave me this problem. I tried and tried, but I couldn't figure it out and the deadline is tomorrow. Please help me out here friends.

In a compound which is made of element Y, weight percentage of Y is 72% and N( Nitrogen) is 28%. Also, 3 Y atoms are bonded with 2 Nitrogen atoms. Find the followings....

(at least I think these are the only equations used.)

The things is that, even though I tried I couldn't approach the question.... I couldn't find a way to enter and continue doing. Therefore there is nothing like an attempt done to solve the problem. I am sorry if this contradicts with your procedure of this specific template.

Please help me out here.

**1. This is the problem :**In a compound which is made of element Y, weight percentage of Y is 72% and N( Nitrogen) is 28%. Also, 3 Y atoms are bonded with 2 Nitrogen atoms. Find the followings....

- Chemical formula of the compound.
- Relative molecular mass of Y.

**2. Relevant equations are :***n of molecular formula = Molar mass/ Formula mass of empirical formula*

number of moles = mass/Molar mass

number of moles = mass/Molar mass

(at least I think these are the only equations used.)

**3. The attempt at a solution :**

The things is that, even though I tried I couldn't approach the question.... I couldn't find a way to enter and continue doing. Therefore there is nothing like an attempt done to solve the problem. I am sorry if this contradicts with your procedure of this specific template.
