You are trying to determine the volume of the balloon needed to match the density of the air in the lab. you know that if you can get the balloon's density below this value, it will float. you measure both the temperature in the room as well as the mass of the balloon you will use and find they are 20.0°c and 0.577 grams, respectively. what volume of balloon will generate a density equal to that of the air around it?

what is your question? collegechemistry 5+3 pts in november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
