Question
At 752 mm Hg of total Pressure and 301 K Temperature 150 ml H2 is produced and collected over the water, when current is passed through acidic water for 1 hour. How many Amp. current should have passed? ( at 301 K temperature, The pressure of water is 28 mm Hg )
A) 0.320 A
B) 310 A
C) 321 A
D) 0.305 A
please mention correct answer.
Solution by Joshi sir.
by formula PV/T = constant
(752-28)*150/301 = 760*V/273
solve for V, this will be the equivalent volume at STP
now convert this volume in gm by the formula 2V/22400
then finally m = zit, where
z = 1/96500
solve it for i
