16. Calculate the empirical formula of compound that contains \( 18.3 \% \mathrm{H} \) and \( 81.7 \% \mathrm{C} \) 17. What is the mass of \( \mathrm{O}_{2} \) is needed to produce \( 36 \mathrm{~g}_{\mathrm{g}} \) of \( \mathrm{H}_{2} \mathrm{O} \) \[ 2 \mathrm{C}_{2} \mathrm{H}_{6}+7 \mathrm{O}_{2} \rightarrow 6 \mathrm{H}_{2} \mathrm{O}+4 \mathrm{CO}_{2} \] 18. How many grams of \( \mathrm{NH} 3 \) will be produced when \( 2.018 \mathrm{~g} \) of \( \mathrm{H} \) and \( 28 \mathrm{~g} \) of \( \mathrm{N} \) is reacter \[ \mathrm{N}_{2}+3 \mathrm{H}_{2} \rightarrow 2 \mathrm{NH}_{3} \] 19. List the factors that increase gas pressure? 20. A volume of air at \( 275 \mathrm{~K} \) decreases from \( 20.0 \mathrm{~L} \) to \( 5.0 \mathrm{~L} \). What is the final temperature?
