A student is told the barometric pressure is known to be 1.04 atm. In her experiment she collects hydrogen gas in a graduated cylinder as described in this experiment. She finds the water level in the graduated cylinder to be 4.5 cm above the surrounding water bath. What is the total pressure inside the graduated cylinder in torr?

dip it in water

Explanation: dip it in water

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
