Astudent submerges an irregularly object in a graduated cylinder half filled with water. the level of the water in the cylinder rises from 17.8 ml to 49.7 ml. if the density of water is 0.9984 kg/liter, calculate the mass of the object in grams. the use of correct number of significant figures is required in answering all questions.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
