Question

A 10 litres bulb contains 8.0 gram of an ideal gas at pressure P atm and temperature T K. the bulb was heated to (T + 175)K when 1.6 gram of the gas was removed from the bulb to keep original pressure. find out the values of P and T if molecular weight of the gas is 80 gram / mole​

Answer 1

Answer:

when 1.6 gram of the gas was removed from the bulb to keep original pressure. find out the values of P and T if molecular weight of the gas is 80 gram / mole

Answer 2

Explanation:

Initial moles, n=

Final moles, n

= 3.6−0.6/44= 3.0

Since P and V are constant,
