If 10 kg of rock salt is placed in water, it dissolves at a rate proportional to theamount of salt still undissolved. If 2kg dissolve during the first 10 minutes, how long will it be until only 2kg remain undissolved?
In Europe, nutritional information is given in kilojoules instead of nutritional calories. A
packet of soup has the following nutritional information:
250 ml of soup = 235 kilojoules
How would that same packet be labeled in the US if the information has to be given in
nutritional calories per cup? (2 cups to 1 pint)
In the tank of 143 liters of brine containing 50kg totally dissolved salt. Pure water is allowed to run into the tank at the rate of 3 liters per minute. Brine runs out of the tank at rate of 2 liters minute. The instantaneous concentration in the tank is kept uniform by stirring. How much salt is in the tank at the end of 1 hour?
