In summary, using the ideal gas law, we can determine the number of moles of gas in a 7.71 liter vessel at a temperature of 18.6oC and a pressure of 8.35 atm. We can use the formula # of moles = (pressure * volume) / (gas constant * temperature) to find that t...

Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...
So a general simple rule is that: the molecule will not be planar if there is ansp3 hybridized carbon (or nitrogen) atomor two sp2 hybridized atoms of carbon/nitrogen which are separated by an even number of double bonds and no single bonds. Otherwise, its structure allows it to be plana...
Grams to Moles Conversion Problem Problem Determine the number ofmolesof CO2in 454 grams of CO2. Solution First, look up theatomic massesfor carbon and oxygen from theperiodic table. The atomic mass of C is 12.01, and the atomic mass of O is 16.00. The formula mass of CO2is: ...

Lewis structures were proposed by Lewis to explain the bonding between atoms and the position of valence electrons around the atoms. It also helps in understanding the structural aspects of the molecules by showing lone pairs as well as valence electrons around each a...
suppose you wanted to determine the moles of aspirin in a 250 mg aspirin tablet. Typing “aspirin” into the NIST database reveals that the drug’s chemical name is 2-acetyloxy-benzoic acid and its molecular formula is C9H8O4. This indicates that one aspirin molecule contains nine carbon ...
For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...
