Question

if the mass of a solid is 31.2 gram and if the English shall and final volume of water level is graduated cylinder when image is 52 ml and 48 ml respectively find the density of the solid convert that into kg by M3​

Answer 1

${\mathfrak{\purple{\underline{\underline{Solution:-}}}}}$

We know that,

Density = Mass/Volume

Here,

volume = Final volume - Initial volume

Therefore using this formula;

Density = 31.2g/52mL - 48mL

= 31.2/4

=7.8g/mL

In order to convert g/mL into kg/m3 we multiply the result with 1000,

= 7.8g/mL × 1000 = 7800 Kg/m3
