Step-by-step explanation:
3.)
The given values:
Mass, m = 100.0 g
Density, d = 1.59 g/mL
As we know,
→ D = m/v
By substituting the given values, we get
v = m/d = 100/1.59
v = 62.89 ≈ 63mL
4.)
The experiment makes use of Archimedes' principle, where the volume of a liquid displaced by an object, is equal to the volume of said object.
Thus, the volume displaced by the object is:
46.9 mL - 25.0 mL = 21.9 mL
The volume of the object is 18.9 mL
Density is equal to the mass divided by the volume, so:
D = m/V = 53.5 g/21.9 mL
D = 2.44 g/mL
5.)
For water,
ρ density = 1.0 g/mL
v = 425 mL
d = m/v
m = d × v
m = 1 × 425 = 425 g
