torr . It is given that 5 0 ml of a certain sample of H 2 O 2 gives 1 2 0 0 ml of O 2 at STP. Volume strength is the volume of oxygen at STP given by one volume sample of hydrogen peroxide on heating. If 5 0 ml of H 2 O 2 gives 1 2 0 0 ml of O 2 , then v olume strength will be = 5 0 1 2 0 0 = 2 4 V A sample of oxygen occupies 47.2 liters under a pressure of 1240 torr at 25C. What volume would it … A sample of 0.100 mol magnesium metal and an excess of aqueous hydrochloric acid are combined and react to completion. How many liters of hydrogen gas, measured at STP, are produced?
