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
