The volume of the gas when the pressure of the gas increases to 755mm hg is calculated as follows
by use of boyles law formula that P1v1=P2V2
V2= P1V1/P2
V1=5.58 L
P1= 715 mm hg
P2=755 mm hg
V2 is therefore= ( 715 mm hg x 5.58 L) /755 mm hg= 5.28 L
Density = mass / volume
Because the dimensions of the barometer are the same for each case, we can compare the heights of the liquids instead of the volume.
ρ(mercury) = 13.6ρ(water)
mass(mercury)/760 = 13.6 x mass(water)/Height(water)
Masses of the liquids will also be the same.
Height of water = 13.6 x 760
Height of water = 10,336 mm
Answer:
gram
Explanation:
Gram is a SI unit (International Ststem of units)
other SI units : kg , meter, ampere, Kelvin
pound gallon and foot are SAE (or imperial) units
