To answer this, you will need to use Charles law which relates volume to temperature in two proportional situations. V1/T1 = V2/T2 = > V2 = V1/T1 * T2 Using the information given, V1 = 1.9 m3 T1 = 32.0 C T2 = 18.0 C we can get the following: V2 = 1.9/32 * 18 = 1.06875. Using the correct number of significant figures, the volume that would be taken up by the existing ethanol after the temperature change is 1.07. If the capacity is 1.9 m3, then the amount of additional that can be added is 1.90-1.07 which is 0.83 m3.
