A steel ball with a volume of 6 cm³ has a mass of 46.8 g. What is the mass of a ball of the same salt if its volume is 2.5 cm³

Let’s remember the density formula from physics: p = m / V.
1) Find the density of the steel:
p = m / V;
p = 46.8 / 6 = 7.8 g / cm3.
2) Find the mass of the second ball made of the same steel:
m = pV;
m = pV = 7.8 * 2.5 = 19.5g.
Answer: m = 19.5g
