the density of carbon tetrachloride is 1.595 g / cm, what is the mass of 20.0 cm of ccl? 2. a liquid has a specific gravity of 0.50. what is its density in g / cm? what is its specific volume in cm / g? what is its density in lb, / ft "? what is the mass of 30.0 cm * of this liquid? what volume is occupied by 18g?

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Burned piece of steel wool does not gain mass. so only d could be true.
