3. A given sample of gas has a volume of 4.20 L at 60.000 and 1.00 atm pressure. Calculate its pressure if the volume is changed to 5.00 L and the temperature to 270C.
Please help

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
