Explanation / Answer

Ans 1

Density of mercury

= (13.534 g/cm3) x (100cm/m)3 x (1kg/1000g)

= 13534 kg/m3

Ans 2

Volume of mercury = 20 mL

Mass of mercury = volume x density

= 13.534 g/cm3 x 1cm3/mL x 20 mL

= 270680 g

Ans 3

Mass of mercury in kg = 270680 g x 1kg/1000g

= 270.68 kg

Ans 4

Pressure = density x g x height

= 13534 kg/m3 x 9.81 m/s2 x 10 ft x 1m/3.28ft

= 404782.13 Pa x 14.7 psi/101325Pa

= 58.725 psi

Ans 5

Gallons of mercury = 10 mL x 1 gallon/3785.41 mL

= 0.002641 gallons

Ans 6

Specific gravity = density of mercury/density of water

= 13.534/0.9970480

= 13.574
