Keep using 22.4 L / mol and each compounds molar mass to solve the rest of the problems. Also remember Avogadro's number, that there are 6.022*10^23 molecules per mole for the last 2 problems. If you need further assistance, please book a session with me! Upvote • 1 Downvote Commen...
Once you have identified the solute and solvent in a solution, you are ready todetermine its concentration. Concentration may be expressed several different ways, usingpercent composition by mass,volume percent,mole fraction,molarity,molality, ornormality. Percent Composition by Mass (%) This is the...

The wavefunction tile reproduces traditional bonding motifs in simple molecules such as water, N2, O2, H2CO and C2H4. The qualitative nature of the tiles, of systems tested so-far, have been found to be insensitive to the size of the basis set beyond 6-31G(d)15. However, some inherentl...
These values can be obtained through various methods such as mass spectrometry, NMR spectroscopy, or chemical synthesis.What are some potential sources of error when calculating Log(MW) and MW with LINEST? Some potential sources of error when calculating Log(MW) and MW with LINEST include ...

However, these all electrons have the same mass and the same charge. Each electron in an atom has a different amount of energy. Electrons with the lowest energy are closest to the nucleus, where the attractive force of the positively charged nucleus is the greatest. ...
In the third example, the formation of a contact pair of cholesterol molecules is examined using two variables: The distance between the center of mass of the cholesterol molecule and their relative orientation while embedded in a DMPC membrane. In the three examples, we used a long time ...
