The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents Where "n" number of equivalents is the quantity of charge depending on the substance. If the substance is an element, ion, acid, base, or ionic compound, it will determine "n". ...

Among these, sn-2 palmitate is a successfully produced structured TAG that has been added to infant formula as a nutritional supplement by many manufacturers. In addition to PA, it is necessary to study and modify the minor fatty acids to achieve a similar positional distribution to that of ...
To calculate a milliequivalent (mEq) you have to have two pieces of information: The mass of the substance in question and the molar mass (or molecular weight) of that substance. You must also be able to identify its valence from its molecular formula, a
The mass of the Earth's atmosphere creates an atmosphere pressure that varies somewhat with elevation and weather conditions but remains relatively constant at sea level. We define the average sea level pressure as one atmosphere of pressure, which makes comparisons ...
Caffeine a stimulant found in coffee has the mass composition of C, 49.48%; H, 5.19%; N, 28.85%; O, 16.48%. The molar mass of caffeine is 194.19 g/mol. Find the molecular formula for caffeine. The molecular weight of vincristine, a pharmac...
where 𝑁N is the number of stack cells, 𝑀𝐻2MH2 is the molar mass of hydrogen, and 𝑛n is the number of charges transferred per mole of hydrogen. The hydrogen filling price at hydrogen refueling stations is 4 USD/kg [38], so the hydrogen cost factor 𝛿1δ1 is taken as ...
