Once the researcher had obtained this information, the researcher was then able to apply the following formula to work out the primer concentration in moles/liter [1]. Concentration in moles/liter (C) = (dilution factor × A260) ÷ (sum of ext...
convert the given concentrations into molarity. here the amount of pcl 5 before the reaction is 6 moles and the volume of the reaction vessel is 1 l. therefore, the concentration of pcl 5 is 6/1 moles/litre = 6 m. step 3 : make a note of the initial concentration and the change ...
Calculate moles of KOH and Mg(NO3)2. From stoichiometry of reaction find moles of reagent in excess and moles of Mg(OH)2 and KNO3. Neglect Mg(OH)2 (precipitate) and finally calculate concentration (volume was changed). Logged AWK
Quote from: steph_r on July 25, 2008, 09:59:19 AM At school we use:N = n / NA, meaning :no. of particles = no. of mole / Avogadro's constant It is right if you take:n = number of particles/molecules/ionsN = No. of molesNA = Avagadro's numberI think you just mixed up...
Protein concentration results can be expressed as 渭g/mL or as moles... Sukumaran,Suja - 《Journal of Visualized Experiments Jove》 被引量: 5发表: 2011年 SILICA PARTICLE COMPOSITION FOR EXTRACTING NUCLEIC ACID OR PROTEIN silica particles in an aqueous solution by suspending the silica particles ...
Any help/advice is much appreciated! -Stef So I would find the moles of CaC2O4? Which I've equated to: = 0.3056g/128.097g/mol = 2.386x 10-3 Then would the mass of Ca2+ions be m=nMr? So,m = nMr = 2.386 x 10-3× 40.078 = 9.561 x 10-2g?
(Calculate moles first by n=m/Mr then use that to calculate the concentration in the 1 L solution by C=n/V, for each salt.) We can talk about what to do next after but it's likely that if you're desperate for an exact answer you'll need to read up. ...
