Measuring Density with Laboratory Balance (mt.com)

Meet van voor werp A en B de dichtheid en vergelijk deze met de literatuur (tabel 8 en 10A binas)

Rapporteert wat stof A en wat stof B is.

The solid is weighed in air (A) and then again (B) in the auxiliary liquid with a known density. The density of the solid ρ can be calculated as follows:

ρ = Density of the sample

A = Weight of the sample in air

B = Weight of the sample in the auxiliary liquid

ρ0 = Density of the auxiliary liquid

ρL = Density of air

The temperature of the liquid must be taken into account as this can cause density changes of the order of magnitude 0.001 to 0.1 per °C, the effect
of which can be seen in the third decimal place of the result.
