Answer:

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
