Initial data: m (alloy weight) = 300 g; V (the volume that the alloy occupies) = 800 cm ^ 3.
SI system: m = 300 g = 300/1000 kg = 0.3 kg; V = 800 cm ^ 3 = 800 * 10 ^ -6 m ^ 3.
We calculate the density of the unknown alloy using the following formula: ρ = m / V.
Let’s make a calculation: ρ = 0.3 / (800 * 10 ^ -6) = 375 kg / m ^ 3 (such an alloy cannot exist).
Answer: The density of the alloy is 375 kg / m ^ 3.
