(a) Two of the simplest compounds containing just carbon and hydrogen are methane and ethane. Given that methane contains 0.3357 g hydrogen for every 1.00 g carbon and that the ratio of g hydrogen/1.00 g carbon in methane to g hydrogen/1.00 g carbon in ethane is 4:3, determine the number of grams of hydrogen per gram of carbon in ethane. (b) Xenon $\left(\text{Xe}\right)$ and fluorine (F) can combine to form several different compounds, including ${\text{XeF}}_{\text{2}}$, which contains 0.2894 g fluorine for every gram of xenon. Use the law of multiple proportions to determine n, which represents the number of F atoms in another compound, ${\text{XeF}}_{\text{n}}$, given that it contains 0.8682 g of F for every gram of $\text{Xe}$.
