где ρ - плотность твердого тела;
ρж - плотность вспомогательной жидкости;
m - масса твердого тела;
m1 - масса мерной емкости;
U1 - объем мерной емкости;
m2 - масса заполненной мерной емкости.1. The method of determining the density of solids, providing for measuring body weight by weighing it in air, placing the body in a measuring tank and determining its volume by means of auxiliary liquid with a known density filling this tank, characterized in that the mass of the measuring tank is previously measured by weighing in air, a solid body is placed in a measuring tank before filling it with auxiliary liquid, the mass of the filled measuring tank is measured by weighing in air, and the desired value is found by athame weighing, from the expression:
where ρ is the density of the solid;
ρ W - the density of the auxiliary fluid;
m is the mass of the solid;
m 1 is the mass of the measured capacity;
U 1 is the volume of the measured capacity;
m 2 is the mass of the filled measuring tank.
