## Chemistry 12th Edition

We know that, using Avogadro's law, the mole ratio and the volume ratio of gases are the same; thus, both are diatomic molecules, and the ratio can be determined by balancing the equation: $1Cl_2+3F_2\rightarrow 2Cl_xF_y$ Thus, by the above equation: x=1 and y=3, making it: $ClF_3.$
