A 36.65g sample of solid is placed in a flask. Toluene in which the solid is insoluble ,is added to the flask so that the volume of solid and liquid together is 50.00mL.The solid and toluene together weigh 58.58 g .The density of toluene at temperature of the experiment is 0.864g/ml .what is the density of the solid?

Respuesta :

The density of the solid is =0.3076g/ml

Calculation of the density of solid

The mass of solid in flask = 36.65g

The volume of both solid and Toluene = 50ml

The mass of both solid and Toluene = 58.58g

The density of toluene = 0.864g/ml

The density of the solid = X

Note: The density of the solid is calculated from the density of both the solid and toluene.

But the density of solid+ toluene;

=mass/volume

= 58.58g/50ml

= 1.1716g/ml

Therefore the density of solid alone = density of both solid +toluene - density of toluene.

= 1.1716g/ml - 0.864g/ml

= 0.3076g/ml
