The tesseract was a crystalline cube which formally held the space stone within the marvel comic universe. for this question, let's assume the tesseract is made entirely of carbon. (a) naturally carbon exists as c2 and cl3 isotopes. the fraction of carbon isotopes in the tesseract is 80% (c2) and 20% (c3), respectively. calculate the molar mass of the tesseract. here percentages are given as atomic fractions. (b) if the tesseract weighs 10g, determine the number of moles and number of carbon atoms in the tesseract. for this problem, use the molar mass calculated in (a). (c) what is the atomic fractions of c2 and cl3 in carbon found naturally on earth, which has a molar mass of 12.01 g/mol. for this problem, you may assume that "earth" carbon is only formed from c2 and c3

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

What is the mass of 0.750 mole of aluminum oxide, al2o3?

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.
