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
