1,000
Gasoline
750
Glycerin
1,260
Olive oil
920
Mercury
13,500

Calculate the mass of 7 L of mercury.
Part 1
I know that the mass of one liter of mercury is equal to:
13,500 L
/
13,500 g
.
I know that the mass is
proportional
/
equal
to the volume.
Part 2
I use a table:
m (kg)
/
m (L)
13,500
?
V (kg)
/
V (L)
1
7
Part 3
Calculation and result:
m =
13,500 × 7
/
13,500 / 7
m =
94,500 g
/
1,929 g
Part 4
Conclusion:
The mass
/
The volume
of 7 L of mercury is equal to
94,500 L
/
94,500 g
.
RESULT:
