Ответ:
1704.54 kg/m³.
Explanation:
The density of a substance is its mass per unit volume.d = m/V.
where, m is the mass of the substance.
V is the volume of the substance.
We will calculate the density in SI unit system (kg/m³).m = 0.045 kg.
V = 26.4 mL/10⁶ = 2.64 x 10⁻⁵ m³.
∴ d = m/V = (0.045 kg)/(2.64 x 10⁻⁵ m³) = 1704.54 kg/m³.
