Find the volume of a zinc bar weighing 700 g.

1. Let’s translate the values from given to the SI system:
m = 700 g = 0.7 kg
2. Let us write down the formula for determining the mass, through the specific gravity:
m = ρ * V
3. Let us express the volume from this expression:
V = m / ρ
4. Let’s find from the reference book the specific all zinc:
ρ = 7100 kg / m³
5. Substitute the numerical values into the expression from paragraph 3:
V = m / ρ = 0.7 / 7100 = 9.86 * 10-5 m³
Answer: the volume of the zinc bar is 9.86 * 10-5 m³ (0.0000986 m³).
