What is the volume of balloon of gas at 2.7 atm and -30.0oC if it’s volume is 915mL at pressure of 1.9 atm and a temperature of 25.0oC?

your answer would be a. 12.5 kg

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

they are all solids.
