1. What is the density of a 30.00-g object that is immersed in a graduated cylinder whose water volume rises from 30.0 mL to 40.1 mL?
2. A flask that weighs 280.5 g is filled with 150.0 mL of NaCI solution. The total weight of the flask and NaCI solution is found to be 304.6 g. Calculate the solution density.
3. Three beakers contain different volumes of water of 8.1 cm3, 0.64 L, and 2.7 dL. If all three volumes were mixed together in a larger container, what would the final volume in mL be?
4. What is the volume of a 0.350-lb sample of ethyl alcohol if its density at the temperature in question is 0.789 g/mL?
5. The usual dose of amoxicillin for children and babies older than 3 months, who weigh less than 40 kg, is 20 to 40 milligrams (mg) per kilogram (kg) of body weight per day, divided and administered every 12 hours. If the drug amoxicillin is 125 mg / 2.5 mL oral suspension, how many teaspoons in 24 hours should be given to a child who weighs 83 pounds for the maximum dose? (One teaspoon is 5 mL)
