I want to create water out of 45.4 Liters of Oxygen at STP. How much water will I produce? STP: Standard Temperature and Pressure
72g H2O
36g H20
9g H20
18g H20

72.96 of water produce by 45.4 L of oxygen at STP.

Explanation:

1 mole of oxygen=22.4 L at STP

\mole of oxygen=22.4/2=11.2 L

11.2 L of oxygen required to produce water=1 mole

1 L of oxygen required to produce water=1/11.2 mole

45.4 L of oxygen required to produce water=

45.4 L of oxygen required to produce water=moles

1 mole of water=18 g

moles of water=

moles of water=72.96 g

Hence, 72.96 of water produce by 45.4 L of oxygen at STP.
