The number of moles of compound is given. By using the number of moles, the mass of nitrogen in each compound given in exercise 51 is to be determined. Concept introduction: The atomic mass is defined as the sum of number of protons and number of neutrons. Molar mass of a substance is defined as the mass of the substance in gram of one mole of that compound. The molar mass of any compound can be calculated by adding of atomic weight of individual atoms present in it. The amount of substance containing 12 g of pure carbon is called a mole. One mole of substance always contains 6 .022 × 10 23 atoms. Hence, ( 6 .022 × 10 23 atoms ) ( 12 u 1 atom ) = 12 g ⇒ 1 u = 1 6 .022 × 10 23 g To determine : The mass of nitrogen ( N ) in 5 .00 moles of NH 3 .

What is the missing intermediate 1 and the final product 2. Please include a detailed explanation explaining the steps of malonic ester synthesis. Please include drawings of the intermediate and how it occurs and how the final product is former.
What would be the reagents and conditions above and below the arrow that will complete the proposed acetoacetic ester synthesis? If it cannot be done efficiently, then I will choose that answer. There could be 2 or 4 reagents involved. Please provide a detailed explanation and drawings showing how it would proceed with the correct reagents.
For benzene, the ∆H° of vaporization is 30.72 kJ/mol and the ∆S° of vaporization is 86.97 J/mol・K. At 1.00 atm and 228.0 K, what is the ∆G° of vaporization for benzene, in kJ/mol?
