Do a quick conversion: 1 grams He = 0.24983748071879 mole using the molecular weight calculator and the molar mass of He.
aThe oxygen balance of an explosive is the mass of oxygen either in excess (i.e. the balance is positive) or in deficit (i.e. the balance is negative)of that required for complete oxidation of C and H. The oxygen balance is expressed as a percentage of the molar mass of the explosiv...
However, a rapid catalyst deactivation occurred with a sharp decrease of the conversion of acetic anhydride, and this was mainly caused by 4-MAP and heavy compounds ('coke') existing in the zeolite pore, which poisoned the active sites of the catalyst. The use of excess toluene and moderate...
Polymerization of aniline was carried out at room temperature in a 40 mL, 0.1M phosphoric acid buffer solution, which contained a 1:1 molar ratio of SPS (MW 1,000,000; moles correspond to quantity of monomers units) to aniline 0.167 g (0.81 mmol). SPS was added first to the buffered ...
died on the scene, gun in hand, and though the police were making inquiries about the car that ran him down, I knew they hadn't even made it as far as interviewing me. Now here was Pete saying he'd been privy to the Saint's dying conversion. "Let's go in the bedroom," I ...
To investigate this possibility, we determined the intracellular pool of GSH in K562 cells treated exogenously with a molar excess of GSH, in the absence and presence of hemin. NAC, as a donator of cysteine, was used as a known substrate for GSH biosynthesis [43,44]. Neither NAC nor GSH...
Dynamic conversion systems, which are revered for their superior efficiency and power density, find widespread application in the space domain. Among them, the closed Brayton cycle (CBC) boasts heightened energy conversion efficiency, enhanced mass-specific power, and a reduced number of moving ...
Catalysts that were prepared under optimal conditions of a molar ratio of (MPTMS)/ (MPTMS+TEOS) of 1:10, a molar ratio of (H 2 O 2 )/(MPTMS) of 18:1 and a mass ratio of (HPW)/(TEOS) of 1:10 exhibited an excellent catalytic activity in the esterification reaction of cyclohexene ...
Molar mass of water (Kg/mol) \(\dot{m}\) : Evaporation–condensation rate of water (Kg m−2 s−1) Q : Energy transferred by heat exchange (J s−1) n : Molar amount (mol) P B : Liquid pressure on the external side of the bubble wall (Pa) V : Volume of the bu...
The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance....
