What is the molecular weight of tris thiourea copper 2 sulphate?
677.86798Da ------------------------- For the chemical formula Cu[CS(NH2)3]3SO4 the molecular weight is 387,857 73.
How do you convert 20mM tris-Hcl to gm?
let we have to calculate wait of 20mM tris-HCL for a solution of 1liter,then formula for molarity is Molarity= weight (in grams)/molecular weight X volume in liter hence 20/1000=wait/121.14X1 wait = 20 X 121.14/1000 (cross multiplication) wait = 2.42gm
How do you prepare 0.1M tris HCl?
To prepare 0.1M Tris-HCl, dissolve 1.21 g of Tris (molecular weight 121.14 g/mol) in distilled water to make 100 mL of solution. Adjust the pH to 7.4 using HCl.
How do you prepare 0.5M Tris-HCL pH 7.2?
To prepare 0.5M Tris-HCl pH 7.2, first calculate the amount of Tris base needed using the molecular weight of Tris (121.14 g/mol). Then dissolve the calculated amount of Tris base in water, adjust the pH to 7.2 using HCl while monitoring with a pH meter, and make up the final volume.
What chemical compound does the abbreviation Tris represent?
Tris is most commonly used as a biochemical buffer. It is also known by the names TRIS, THAM, Trisamine, Tromethamine, Tromethane, Trizma and Trisaminol.

How do you prepare 10mM Tris?
To prepare 10mM Tris solution, first calculate the amount of Tris base needed based on the molecular weight of Tris (121.14 g/mol). Weigh out the appropriate amount of Tris base and dissolve it in water to make a final volume of 1L. Adjust the pH to the desired value if necessary.

What is the difference between tris and tris hcl?
They are all basically the same thing. Tris-HCl is just the Tris base converted to a salt with HCl. You can buy either one. The advantage of starting with powdered Tris-HCl is that it is more soluble in water than the base and as a solution has a more neutral pH which is usually the desirable buffer point. Tris base has a pKa of over 8 so using Tris-HCl saves you the trouble of bringing it to a more neutral pH. The one thing to be careful of when making solutions from powder is to be sure to use the correct molecular weight which differs between the two. To answer your specific question, it doesn't matter which you start with except in the rare cases where the sodium from the NaOH would be an issue. For your situation where the solution is going to be slightly basic, it sounds like you could use either one as the starting reagent. I would go with whatever is already around the lab.

What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
How do you make 62.5 mM Tris-HCl?
To make 62.5 mM Tris-HCl solution, you would need to mix the appropriate amount of Tris base and HCl to achieve a final concentration of 62.5 mM. The calculation involves considering the molecular weights of Tris and HCl to determine the amount needed to make the desired concentration.
What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
Represent the protonation of Tris base by Hcl?
When Tris base is protonated by HCl, the amine groups on the Tris molecule will accept a proton (H+) from the hydrochloric acid, forming TrisH+ and chloride ions as a counterion. This results in the formation of Tris hydrochloride, a water-soluble salt commonly used in biochemistry and molecular biology experiments.
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
