The density of water is 1.0g/cm*3. This is useful as it means we can measure the mass of water and easily work out its volume.
a. What is the mass of 1cm*3 of water?
b. What is the mass of 20cm*3 of water?
c. What is the volume of 10g of water?
d. What is the volume of 22.5g of water?
e. Milan is measuring the density of ethanol. He weighs a bottle three times: first, empty;
then filled with ethanol. Here are his results:
mass of empty bottle = 30.0g
mass of bottle filled with water = 90.0g
mass of bottle filled with ethanol = 78.0g
i. Calculate the volume of the bottle.
ii. Calculate the mass of the ethanol.
iii. Calculate the density of ethanol.
