Answer 1

Answer #1

a. Barometric pressure = 29.94 in Hg

1 in Hg = 25.4mmHg

Barometric pressure = 29.94*25.4 mmHg

= 760.476mmg

= 760.476/760

= 1.00063atm >>>>>answer

b. water vapor pressure at 22⁰C = 19.8mmHg

= 19.8/760

= 0.026atm >>>>answer

c. The pressure of hydrogen in atmosphere = Barometric pressure - water vapor pressure at 22⁰C

= 1.00063-0.026

= 0.97463atm >>>>answer

d. volume of hydrogen collected = 57.5ml

= 0.0575L >>>>answer
