Can someone please help? This was due yesterday. The Appendix Table A-8 is linked in a photo. And do it right please. Don't say "eXpLaNaTiOn iS iN tHe FiLe" like someone else did. No explain it here. A certain mass of oxygen was collected over water when potassium chlorate was decomposed by heating. The volume of the oxygen sample collected was 720. mL at 25.0° C and a barometric pressure of 755 torr. What would the volume of the oxygen be at STP? (Hint: First calculate the partial pressure of the oxygen, using Appendix Table A-8. Then use the combined gas law.)
