EXPERIMENT : DENSITY

Pre$-$Lab Exercises:

What is the difference between precision and accuracy in the context of making measurements?

A student determined the mass of a graduated cylinder to be $31\mathrm{.}4118g.$ The correct value for the mass of the graduated cylinder is $31\mathrm{.}4231g.$ What is the $\%$ error in this measurement?

a$)$ Volume of a rectangular box;

b$)$ Volume of a cylinder;

c$)$ Volume of a sphere

$5.$ The volume of water in a graduated cylinder was recorded as $31\mathrm{.}9mL.$ After a metal sample was immersed in it$,$ the volume rose to $58\mathrm{.}9mL.$ What is the volume of the metal sample in the correct significant figures? If the metal weighs $72\mathrm{.}8g,$ what is its density?
