Interpretation:
The mass of single
Concept introduction:
Mass of one atom is equal to the mass of total protons, neutrons, and mass defect.
Mass defect refers to difference in the mass of an atom and the sum of mass of protons, electrons, and neutrons present in the atom.
Energy is given by the following expression:
Here,
The number of neutrons is calculated as
The number of nucleons is calculated as
The relationship between and can be represented as
To convert the mass from amu to kilograms, conversion factor is
The mass of atom is calculated as
Here,

- Identify and provide an explanation of what 'Seperation Science' is. Also describe its importance with the respect to the chemical analysis of food. Provide specific examples.arrow_forward5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn.

- An orange laser has a wavelength of 610 nm. What is the energy of this light?arrow_forwardThe molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues: Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550. Predict the molar absorptivity of transferrin. Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet. Estimate the g/L of a transferrin solution with an absorbance of 1.50 at 280 nm.arrow_forwardIn GC, what order will the following molecules elute from the column?

- Beer’s Law is A = εbc, where A is absorbance, ε is the molar absorptivity (which is specific to the compound and wavelength in the measurement), and c is concentration. The absorbance of a 2.31 × 10-5 M solution of a compound is 0.822 at a wavelength of 266 nm in a 1.00-cm cell. Calculate the molar absorptivity at 266 nm.arrow_forwardHow to calculate % of unknown solution using line of best fit y=0.1227x + 0.0292 (y=2.244)arrow_forwardGiven a 1,3-dicarbonyl compound, state the (condensed) formula of the compound obtaineda) if I add hydroxylamine (NH2OH) to give an isooxazole.b) if I add thiosemicarbazide (NH2-CO-NH-NH2) to give an isothiazole.arrow_forward
