The approximate minimum daily dietary requirement of the amino add leonine, c6hi3no2, is 1.1 g, what is this requirement in moles? A 55-kg woman has 7.5 times 10^-3 mol of hemoglobin(molar mass = 64, 456 g/mol) in her blood. How many hemoglobin molecules is this? What is this quantity in grams? Determine the percent water in CuSO_4-5H_2O to three significant figures. Dichloroethane, a compound that is often used for dry cleaning, contains carbon, hydrogen, and chlorine.It has a molar mass of 99 g/mol. Analysis of a sample shows that it contains 24.3% carbon and 4.1% hydrogen. What is its molecular formula? Consider this question: What is the morality of KMnO_4 in solution of 0.0908 g of KMnO_4 in 0.500 L of solution? (a) Outline the steps necessary to answer the question.(b) Answer the question. If 4.12 L of a 0.850 M-H_3PO_4 solution is be diluted to volume of 10.00 L, what is the concentration the resulting solution? Find the molarity of a 40.0% by mass aqueous solution of sulfuric acid, H_2SO_4, for which the density is 1.3057 g/mL
