Why do we convert grams to moles? Scientists use moles because moles are an easy and consistent way to work with large numbers of particles. In addition, using moles ensures that comparisons are being made between equal numbers of atoms or molecules. Using grams in calculations instead of moles...
For sucrose, multiply the mass of hydrogen (which is about 1) by the number of hydrogen atoms (22) in sucrose. You may need to use moresignificant figuresfor the atomic masses for your calculations, but for this example, only 1 significant figure was given for the mass of sugar, so one...

1. A process for preparing a built-up linear condensation polyester of a glycol having from 2 to 8 carbon atoms and an aromatic dicarboxylic acid, said built-up polyester having a molecular weight of at least 14,000 comprising (I) mixing the following constituents under an inert atmosphere ...
The maps were generated using REFMAC561 and correspond to the difference weighted 2mFo-DFc density map, contoured at 1.0σ level, in which the peptide atoms were omitted. N-dom in cyan (interacting residues in stick representation), bound dipeptides in grey stick, catalytic zinc ion and ...
The invention relates to producing biodiesel from palm oil, Rape seed, vegetable and animal product that are all fatty acids with even number of carbon atom typically 12 to 22 atoms. It does not produce sulfur dioxide, less carcinogen fumes and less black smoke. The lack of sulfur in the ...
The process of the present invention allows a gasoline cut possibly comprising hydrocarbons containing two, three or four carbon atoms to be upgraded, thereby reducing the total sulphur content of said gasoline cut to very low levels, compatible with current or future specifications, without substantia...
A nitroparaffin having from 8 to 70 carbon atoms is converted to the corresponding dimethylaminoalkane by reacting with at least two moles of formaldehyde and at least five moles of hydrogen per mole of nitroparaffin in the presence of a hydrogenation catalyst and a solvent for the reactants ...
atoms and three or more hydroxyl groups are converted to alcohols of fewer carbon atoms by catalytic hydrogenation in the presence of an initially added substantially anhydrous mono- or di-hydric aliphatic alcohol containing less than five carbon atoms as vehicle at a pressure not above 3000 lb./...
This is accomplished according to the invention by carrying out the reaction between the substituted or unsubstituted carbonyl compound with at least 2 carbon atoms and least one α-hydrogen atom and the substituted or unsubstituted aldehyde at a carbonyl concentration of at most 6 moles/l of rea...
