A tank of oxygen has a volume of 1650L. The temperature of the gas inside is 35degrees Celsius. If there are 9750moles of oxygen in the tank what is the pressure in PSI?

2193.8 PSI is the pressure in the tank

Explanation:

We apply the Ideal Gases Law to solve this:

P. V = n. R. T

T° is the temperature in K, so we must do the conversion:

35°C + 273 = 308K

P. 1650L = 9750 mol. 0.082 L. atm/mol. K. 308K

P = (9750 mol. 0.082 L. atm/mol. K. 308K) / 1650L → 149.24 atm

Let's make the conversion:

1 atm = 14.7 PSI → 149.24 atm. 14.7 PSI / 1 atm = 2193.8 PSI
