Answer:
the height of a iodododecane barometer column =66.46mm
Explanation:
we will the density of liquid 1-iodododecane and the density of mecury (compare with the given value of mercury)
when the atmospheric pressure is 751 torr ?
the compound 1-iodododecane has a density of 1.2g/mL
the density of mercury is 13.56g/mL
for mercury at
1 torr corresponds to 1 mm of a liquid mercury column= 13.56g/ml
for 1-iodododecane
751toor = ? at 1.2g/mL
1 torr = 1mm = 13.56
751 torr of mercury = 751mm = 13.56
751 toor of iodo = ? = 1.2
751mm = 13.56
? ====1.2
1.2 * 751)/13.56 =66.46mm
the height of a iodododecane barometer column =66.46mm
