> 
> During a chemical reaction, equal moles of two diatomic molecules $\ce{X}$ and $\ce{Y}$ are allowed to react to form one gaseous compound $\ce{X\_nY\_m}$. After the reaction is complete, it was observed that the density of the product formed is $1.50$ greater than the density of the reactant mixture. Specify the formula of the product $\ce{X\_nY\_m}$.

Here is my work: 


$$\ce{X\_m + Y\_n -> X\_nY\_m}$$


Density of product: $D\_\mathrm{p}$ = $(m/V)\_\mathrm{p}$


Density of reactant: $D\_\mathrm{r}$ = $(m/V)\_\mathrm{r}$


\begin{align}
D\_\mathrm{p} &= 1.5 \cdot D\_\mathrm{r} \\
(m/V)\_\mathrm{p} &= 1.5 \cdot (m/V)\_\mathrm{r} \\
m\_\mathrm{p} &= 1.5 \cdot m\_\mathrm{r}
\end{align}


I really dont know where to go from there. I would appreciate it if someone could give me step by step how they solved it so I could not just have the answer but also understand how they got to it. 


Also, would the formula found be empirical or molecular? How do you know that it is?
