number of moles formula mass/molar mass; n=m/M; number of moles equals mass of a substance divided by mass of one mole for example: mole of RFM = to ? RFM is equal to the mass of one mole formula for Mole (n) when mass and RFM are known n = m/RFM formula for finding mass ...
Therefore, Number of moles of H2T =0.0020= 0.0010 moles 2 Concentration = number of moles x 1000 Volume 25 cm3 of wine were used, so… Concentration =0.0010x 1000 = 0.040 mol dm-3) 25 However for red wine i had to do a 1 in 10 dilution to be able to see the indicator change c...
I was just wondering why I can't just figure out the number of moles of Na2SO4 using n=cv and since it is a 1:1 ratio between Na2SO4 and BaCl2 then the number of moles are the same which can be used to find the concentration of BaCl2 using c=n/v. And this concentration woul...
(to convert TSB level to micromoles per liter, multiply by 17.104) of that with continuous PT and no higher than 8.0 mg/dL (a value well below the lowest mean TSB level identified in any clinical trial [9.8 mg/dL3] to increase the risk of neurodevelopmental impairment [NDI] in ELBW ...
Describe the procedure for finding the volume density of atoms in a crystal. Density: The density is known as the term which is the correlation of mass to the volume occupied by the object. The standard international unit of density is kilogram per meter cube and is also used to ...
I have a NxM matrix AA and a wave bb with M rows. Now I'd like to find random elements in a wave cc with N rows such that, if I execute: function foo (AA, cc) wave AA, cc Duplicate/FREE/O AA, frac frac = AA[p][q] *cc[p] MatrixOP/O bb_
The lease has a primary period which covers all or most of the expected useful economic life of the asset. What is this 'primary period'? Why does one multiply the mass of one element in a given compound by the moles of that compound to find the a...
You don't calculate concentration of H2O2 in the titrated solution. Instead, you calculate number of moles of H2O2 titrated, and as you know volume of aliquot of hydrogen peroxide taken, you can calculate concentration in the ORIGINAL sample. So yes, dilution of your aliquot doesn't matter, ...
