If the mass of a material is 45 grams and the volume of the material is 13 cm^3, what would the density of the material be?

It would be 3.462 g/cm (45/13). hope this helps!

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
