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...
let mass of MnO2 be X 2KClO3-> 2KCl +3 O2 from the stoichiometric ratio. the number of moles of KClO3decomposed = number of moles of KCl formed. let the number of moles of KCl formed be N molar mass of KCl = 39.1+35.5 = 74.6g/mol molar mas of KClO3= 39.1 + 3X16 = 87.1g/m...
The formula for finding chemical potential is μ = ΔG/Δn, where μ is the chemical potential, ΔG is the change in Gibbs free energy, and Δn is the change in the number of moles of the substance. 2. What is the concept of chemical potential?
The idea of structured light projection or fringe pattern projection is based on the knowledge of the different behavior of different, well-known patterns, projected on a target and imaged with a stereo camera setup. The used software algorithm, the pattern structure, the number of used patterns,...
(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 ...
Finally, take the sum total of all elements. In Mg3P2, there are 3 magnesium atoms and 2 phosphorus atoms. Therefore, we use the periodic table to find the atomic mass of magnesium (24.3050g) and phosphorus (30.9737g), and multiply each by the number of t...
That should give you the atomic ratio of sulphur to iron in the sulphide, which translates easily to a formula. hmmm kk well where i get lost is when i divide the moles. What i would do is divide big/small and get a decimal number but i don't knw how to convert that into a ...
The Fotofinder unit. Credit: University of Connecticut Grant-Kels recommends that patients with many moles or a family history of skin cancer or melanoma see a dermatologist every six months. "I am glad to report that UConn Health now has every new FDA-approved technology to help patients ma...
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 ...
the titrated solution. Instead, you calculate number of moles of H2O2titrated, 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, as it doesn't change number of moles of H2O2...
