4. The mass of a density bottle is 20 g when empty and 45 g when full of water. When full of mercury its mass is 360 g .
a) i. Calculate the mass of water that fills the density bottle.

m =p × r
=20 × 45
=900 g

ii. Calculate the mass of mercury that fills the density bottle.
(lmk)

m =p × y
=20 × 540
=10800 g

45 g-20 g

=25 y
(2miss)
b) i. Given that the density of water is 1 g / cm^3, calculate the volume of water that fills the density bottle.
(2mk)

r =m / ρ
=(10890)/(1)(10800)/(400)(900)/(1) n=259
=100 cm^3
Give the volume of mercury that fills the dengity borle. ρ=n^3

900-360

=549 .

360 y-209
?3+0

(1mk)

=10800 cm^3=900 cm^3

(2mhs)
iii. Calculate the density of mercury.
