1. ### How many liters of water can be made from 55 grams of oxygen gas and an excess of hydrogen at STP?

at STP, 1mole of any gas occupies 22.4L 2H2 + O2 --> 2H2O 55g / 32g/mole = 1.72moles O2 1.72moles O2 x (2H2O / 1 O2) x 22.4L/mole = 77L

3. ### what is the density of 02 at STP?

1 mole. of O2 = 32g. 1 mole. at STP occupies 22.4L. Density = Mass / Volume. Density of O2 at STP = 32g / 22.4L = 1.43g/L = 1.43kg/m³ have a blast!!!

4. ### what volume will 35g of flourine gas occupy at STP? calculate without using the ideal gas law formula?

At STP 1 mole of any gas occupies 22.4 liter 1 mole F2 is 2 x 19 = 38 gram so 35 gram is (35/38) = 0.92 mole the volume is 0.92 x 22.4 = 20.6 liter
