The mass percent of sugar in the solution is 1.225%
<u><em>calculation</em></u>
mass percent = [(mass of solute /mass of solution ) x 100]
mass of solute ( mass of a substance that dissolve in another substance)
= 2.45 g
mass of solution( mass of a substance that dissolves a solute) =200.0 g
Therefore mass percent = 2.45 g/200.0 g x 100 = 1.225% of sugar in solution
28.01 g/mol is the answer for carbon monoxide (CO)
The element is most likely PHOSPHORUS.
Phosphorus is an element with an atomic number of 15. The electronic configuration of the element is 2,8,5. This configuration implies that, each atom of phosphorus has three sub shell, the first sub shell has 2 electrons, the second has 8 electrons while the outermost sub shell has 5 electrons. The electrons in the outermost shell are also called the valence shell. Thus, phosphorus has 5 electrons in its valence shell.
Answer:
NMR stands for Nuclear Magnetic Resonance, and NMR spectroscopy is the technology that makes use of the phenomena of NMR in the analysis of a material's molecular structure through measurement and observance of the nuclear spin interactions, in order to determine the biological, physical and chemical properties of the material
NMR works by the noting that some atoms in molecules placed in a strong magnetic field display the characteristics of small magnets. The application of a broad spectrum radio frequency to the molecules will cause the nuclei to resonate at particular frequencies. An NMR spectrum is formed from the measured nuclei resonant frequencies such that the graph peaks shows the correct frequencies in the sample and the peak height is directly related to the proportion or number of the nuclei which are resonating to a given frequency, such that the frequency values are indicative of the type of atoms and their distances apart from a given atom
