Suppose we pick two grapefruit at random from the bin. The difference in the weights of the two grapefruit selected (the weight of the first grapefruit minus the weight of the second grapefruit) is a random variable with a mean (in ounces) of

72 is the answer to this problem

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

the answer to this is 4340
