Question

A scuba diver's tank contains .25 kg of oxygen compressed into a volume of 4.3 L (for oxygen, 32g = 1 mole)

Calculate the gas pressure inside the tank at 9 degrees Celsius
What volume would this occupy at 26 degrees Celsius and .95 atmospheres?

Answer 1

Use the ideal gas law. moles O2= 250/molmassO2

P= nRT/V

Answer 2

what would the number of moles equal then? and R= .0821 K atm L mol?

Answer 3

I still don't get it.. lol

Answer 4

.29kg=290g*32g(Molar mass of O2)
