It is given that density of water at 20oC = 0.9982 g/ml and at 0oC = 0.9150 g/cm3 = 0.9150 g/ml .
But we know that,
Density = Mass / Volume -----------------------------(1)
Here the volume of soda can containing water is given to be 333 ml.
At 20oC ,
0.9982 g/ml = Mass / 333 ml ----------------------------------From (1)
Mass of water = 0.9982 * 333 = 332.4 g
Thus the mass of water in soda can at 20oC is 332.4 g .
This mass of water will remain constant even if the temperature of the system decreases.
Hence at 0oC,
0.9150 g/ml= 332.4 g / Volume ------------------------------From (1)
Volume = 332.4 / 0.9150 = 363.27 ml
Thus the volume of can should be 363.27 ml when water in it reaches at 0oC to avoid its explosion.
