Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
The following calculation will give the number of molecules in two moles of water: (2 moles water) x (6.02 x 10^{23}/1 mole) = 1.20 x 10^{24}, Provide the detailed steps and reasons for the calculations to arrive at the final answer on the right-hand ...

The mole is one of the more important concepts in chemistry. In technical terms a mole consists of 6.022 x 1023molecules of a substance. In more practical terms a mole is the number of molecules necessary to have an amount of substance in grams equal to the substance’s molecular weight in...
Molecules form when atoms bond with each other. They either form covalent bonds, in which the atoms join by sharing electrons with each other, or ionic bonds, in which neutrally charged atoms lose electrons, and bond with other atoms to restore balance. The noble gases are outliers because ...
Depressurize the gel while it still remains above its critical temperature. As the pressure decreases, molecules are released as a gas and the fluid grows less dense. Remove the gel from your heat source. After the structure cools, there's too little alcohol to recondense back into liquid, ...
Then the iso-lysergic acid hydrazide is isomerized, which means that the atoms in its molecules are rearranged through a chemical process. It's cooled, mixed with an acid and a base, and evaporated. What remains is iso-lysergic diethylamide, which is isomerized again to produce active LSD....
Molecules are constantly vibrating, and these vibrations change when the molecules absorb IR light. The changes in vibration include the bending and stretching of various bonds. Each type of bond within a molecule absorbs IR at different wavelengths. So, to identify ethanol in a sample, you have...
Diets high in trans fats (most are fats that are made by an industrial process that adds hydrogen to processed foods), saturated fats (types of fat that contain a high level of fatty acid molecules without double bonds), and cholesterol ...
grams of sample = (molar mass) x (moles) Problem Find the number of grams in 0.700 moles of hydrogen peroxide, H2O2. Solution Calculate the molar mass by multiplying the number of atoms of each element in the compound (its subscript) times the atomic mass of the element from the periodic...
