Question
If a bottle of olive oil contains 1.3 kg of olive oil, what is the volume, in milliliters, of the olive oil? Express your answer to two significant figures and include the appropriate units. A cannon ball made of iron has a volume of 116 cm^3. What is the mass, in kilograms, of the cannon ball? Express your answer to three significant figures and include the appropriate units. A balloon filled with helium has a volume of 6.1 L. What is the mass, in grams, of helium in the balloon? Express your answer to two significant figures and include the appropriate units.Explanation / Answer
Density = Mass/Volume
or, Volume = mass/Density
Mass of oliv oil = 1.3kg = 13,00gm
Volume of olive oil = mass of olive oil/ density of olive oil
= 13,00gm/0.92gm/mL = 1.4*10^3 mL
----------------------------------
Density = mass/volume
or, mass = density * volume
mass of the cannon ball = density of iron * mass of the ball
= 7.86 gm/cm^3 * 116 cm^3
=911.76 gm
= 0.912 kg (Answer)
------------------------------------------------------------
Mass of the balloon = density of helium * volume of the balloon
= 0.179 g/L * 6.1L
= 1.0919 gm
= 1.1 gm (answer in two significant figures)
