What volume (L) of a 0.2% NaHCO3 solution can be prepared by diluting 5 L of a 4.2% NaHCO3 solution? Calculate the molarity of a 6.798-g sample of NaHCO3 dissolved in enough water to make 400.0 mL of solution. What is the percent by mass o...
This molar mass calculator will find the molar mass of a compound and show a step-by-step solution including all calculations to get the answer. You can also ask for help in our chat or forums. Examples H3N3O3C3 HeNTaI21 PB(NO3) Na3((AlOH)6) CH3PO2 C7H18NO7P NaHCO3{-} C6H5...
MNaCl+MNaHCO3+Mwater=10g+6g+120g=136g Divide the mass of the first dissolved component by the solution mass, and then multiply the result by 100 to calculate the mass percentage. In our example, the first dissolved compound is NaCl; the mass percent is: ...
For aerobic counts, the total cuturable counts medium was prepared as for the anaerobic counts excluding Resazurin solution, NaHCO3 and Na2S-cysteine. In addition, the medium was not saturated with CO2 and plates were poured in aerobic conditions. Counting precision of the microbiota was maximized...
and H2O2-treated gemmules ofE. fluviatilis(Porifera) were provided by Prof. Noriko Funayama (Kyoto University). Gemmules were cultured in M-medium (1 mM CaCl2, 0.5 mM MgSO4, 0.5 mM NaHCO3, 0.05 mM KCl and 0.25 mM Na2SiO3) at 23–24 °C. To...

Methanomassiliicoccales are a recently identified order of methanogens that are diverse across global environments particularly the gastrointestinal tracts of animals; however, their metabolic capacities are defined via a limited number of cultured strai
Slices were cut in ice-cold solution containing (in mM): 205 sucrose, 10 glucose, 25 NaHCO3, 2.5 KCl, 1.25 NaH2PO4, 0.5 CaCl2 and 7.5 MgCl2. Slices were incubated for 30 min in artificial cerebrospinal fluid (aCSF) at 34°C. The aCSF was composed of (in mM): 125 NaCl, 25 glucose...
