V = 0.5 l = 0.5 * 10 ^ -3 m ^ 3.
ρm = 1030 kg / m ^ 3.
ρрт = 13550 kg / m ^ 3.
ρsp = 789 kg / m ^ 3.
mm -?
mrt -?
msp -?
The mass of a substance is determined by the formula: m = ρ * V, where ρ is the density of the substance, V is the volume of the substance.
mm = ρm * V.
mm = 1030 kg / m ^ 3 * 0.5 * 10 ^ -3 m ^ 3 = 0.515 kg.
mрт = ρрт * V.
mrt = 13550 kg / m ^ 3 * 0.5 * 10 ^ -3 m ^ 3 = 6.755 kg.
msp = ρsp * V.
msp = 789 kg / m ^ 3 * 0.5 * 10 ^ -3 m ^ 3 = 0.3945 kg.
Answer: mm = 0.515 kg. mrt = 6.755 kg, msp = 0.3945 kg.
