Density is defined as mass/volume, looking at this equation you can see that density and mass are proportional (if the density is greater so to must be the mass in order to nake the equation true). so canned goods are denser than paper goods because they have a greater mass yet take up the same volume. So solving a problem would involve calculating the mass, using D=m/v solve for m: m=DxV just multiply the density and volume of the shopping bag and compare the masses. If you dont know the volume of the bag use this equation LxWxH=V

i can answer the third one.

x degrees Celsius plus 273.15 = y degrees Kelvins

simple huh?

so 34 C + 273.15 = 307.15 K
