The volume occupied by 4 . 75 g of acetylene gas at 50 ° C and 740 mm Hg pressure is ____________ L . (Rounded off to the nearest integer) [Given R = 0 . 0826 L atm K - 1 mol - 1 ]

Question

The volume occupied by 4 . 75 g of acetylene gas at 50 ° C and 740 mm Hg pressure is ____________ L . (Rounded off to the nearest integer) [Given R = 0 . 0826 L atm K - 1 mol - 1 ],
