1. A scuba diver's tank contains a certain amount of o, compressed into a volume of 2.3 Land pressure of 91 atm and temperature inside the tank of 9°C. What volume would this oxygen
occupy at 26°C and 0.95 atm?

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
