Determine the density of a substance if it has a mass of 14 kg with a volume of 7 liters.
August 8, 2021 | education
| Initial data: m (mass of substance) = 14 kg, V (volume of substance) = 7 liters.
SI system: V = 7 l = 7 * 10 ^ -3 m ^ 3 (1 l = 1 dm ^ 3 = 10 ^ -3 m ^ 3).
The density of the taken substance is calculated by the formula:
ρ = m / V.
Let’s do the calculation:
ρ = 14 / (7 * 10 ^ -3) = 2000 kg / m ^ 3.
Answer: The density of the substance is 2000 kg / m ^ 3.
