Milan is measuring the density of ethanol. He weighs a bottle three times: first, empty; then filled with water; 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.​
