Mass of 50 mL beaker containing 10 mL of mercury 170 g Mass

Mass of 50 mL beaker containing 10 mL of mercury: 170 g

Mass of emtpy 50 mL beaker: 30 g

i) what is the mass of mercury measured?

ii) Density of mercury?

iii) will a brick with a density of 8 g/ml float in liquid mercury?

Solution

Answer:

i) what is the mass of mercury measured?

Mass of mercury= Total weight -weight of beaker

=170-30= 140g

ii) Density of mercury?

Density=mass/volume

=140g/10mL

=14g/mL

iii) will a brick with a density of 8 g/ml float in liquid mercury?

Yes, Since it has less density than the mercury (14g/mL)
