- How many moles of EDTA (C10H16N2O3) do you have in 785µl of a 74MM EDTA solution (Mr(C10H16N203) = 292.24)? Consider all digits of your Givens significant. Round results to the appropriate number of Significant Digits. The number of moles is mmol.arrow_forward75 mL of 0.300 mol/L sodium phosphate solution is combined with 67.5 mL of 0.350 mol/L calcium bicarbonate. a)Before you begin your reaction, you must accurately produce 1.500 L of your sodium phosphate solution from sodium phosphate trihydrate solid. Write out a procedure to explain all the steps you will take in the lab when making the solution to ensure that your solution concentration is accurate. Please include calculations that show the required mass of solid. Also include the correct names of all equipment used. b)You have a super powerful microscope in your lab! You are able to zoom in on your sodium phosphate solution and take a picture at the molecular level. Label the diagram on the left with the correct choices from the box on the right. You may use arrows or rewrite the symbols in one appropriate place. c)In one sentence, explain what the diagram is showing.arrow_forwardCompound A has molecular formula C7H7X. Its 1H-NMR spectrum shows a singlet at 2.25 ppm and two doublets, one at 7.28 ppm and one at 7.39 ppm. The singlet has an integral of three and the doublets each have an integral of two. The mass spectrum of A shows a peak at m/z = 126 and another peak at m/z = 128; the relative height of the two peaks is 3:1 respectively. Identify what atom X is, explaining your reasoning and identify Compound A, explaining your reasoning.arrow_forward
