A9.55g sample of a solid was placed in a 15mL flask. The remaining volume was filled with benzene in which the solid is insoluble. The solid and benzene together weigh 19.33g. The density of the benzene is 0.876 g/mL. What is the density of the solid?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
A9.55g sample of a solid was placed in a 15mL flask. The remaining volume was filled with benzene in which the solid is insoluble. The solid and benzene together weigh 19.33g. The density of the benzene is 0.876 g/mL. What is the density of the solid?
Given total mass =19.33 g
mass of solid =9.55 g
Thus mass of benzene =Total mass- Mass of solid=(19.33-9.55)g=9.78g
Density of benzene =0.876 g/ml
Therefore volume of benzene =mass of benzene/density of benzene = 9.78g/0.876g/ml = 11.16 ml
Total volume = 15 ml
Volume of solid=Total volume-Volume of benzene=(15-11.16)=3.84ml
Thus Density of solid = mass of solid/Volume of solid
=9.55g/3.84 ml= 2.49g/ml
So the Density of solid is 2.49g/ml.
