A student measures the mass and determines the volume of a cubic object to determine its density. The student recorded a set of data; 2.86 cm, 2.79 cm and 2.82 cm. He massed the object and recorded 23.7 g. The actual density of the object is 0.987 g/cm^3. What is the volume of the cubic object? (Enter the answer to three significant figures. Then enter a space and then enter the correct unit. Please use the abbreviation for the unit and not the word(s). For example, "g" and not "grams".)

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.

The second and last option are the answers

It is a body of knowledge gained  using  inquiry and experimentation 

Use the universal gas law formula: pv = nrt now, the key word in this problem is stp, so at stp, temperature will always be 0 degrees celsius and pressure will always be 1.0 atm or 760 torr. given something is at stp, we already know the two variables pressure and temperature. the other thing we can find with the given information is moles. to find moles, just divide grams by molar mass of the element. 16.0g / 2(16.00)g/mol = 0.5 moles plug the values in to the equation pv = nrt (1.0 atm)( x ) = (0.5 )(0+273=273k) the r value is just a constant for when we use atm, liters, moles and kelvin. i'm assuming you want your answer in liters, but if you dont just move the decimal 3 to the right in your final answer. so when plugging these numbers in to your calculator and trying to find x, you get 11.20665 liters using significant figures the answer is 11.2 liters
