What else can I help you with?
In manufacture of potassium permanganate by electrolysis of k2mno4 what should be the equivalent weight of kmno4 how much kmno4 will be produced by 96478 coulombs or one farady?
Equivalent weight of KMnO4 is equal with molar weight of KMnO4. The some is and for K2MnO4, K2MnO4 - e +OH- --------- KMnO4 + KOH In general, Equivalent weight = Molar weight / Number of electrons that take or give one molecule Equivalent weight of KMnO4 = Molar weight of KMnO4 / 1
What is KOH Molecular weight?
K - 39.10O - 16.00H - 1.01---- = 56.11 g/mol!Just add the three individual atomic masses together to get the molecular mass. Hope this helps.
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.
What is the name of the chemical formula KOH?
The chemical formula KOH stands for potassium hydroxide. It is a strong base commonly used in industry and laboratory settings.
How do you make a 1 percent aqueous solution of potassium hydroxide?
To make a 1% aqueous solution of potassium hydroxide, you would mix 1 gram of potassium hydroxide with 99 grams of water (for a total of 100 grams solution). This would give you a solution where 1% of the total weight is potassium hydroxide.
How many atoms are in 1 gram of KOH?
1 gram of KOH is equivalent to approximately (1.55 \times 10^{22}) atoms. This can be calculated by converting the mass of KOH to moles using its molar mass, and then using Avogadro's number (6.022 x 10^23) to determine the number of atoms in 1 mole of KOH (1 mole = 1 formula unit = 1 formula weight in grams).
What is 'James' in Italian?
Giacomo is an Italian equivalent of 'James'. It's pronounced 'JAH-koh-moh'. The equivalent for a girl is 'Giacoma', which is pronounced 'JAH-koh-mah'.
What is 'small' in Italian?
Piccolo is an Italian equivalent of 'small'. It's the masculine form of an adjective whose feminine equivalent is 'piccola'. They respectively are pronounced 'PEEK-koh-loh' and 'PEEK-koh-lah'.
What is the Italian 'Così così' in English?
So-so is an English equivalent of 'così così'. The Italian word is an adverb. It's pronounced 'koh-SEE koh-SEE'.
How do you prepare 30 percent of methanolic KOH solution?
To prepare a 30% methanolic KOH solution, you would mix 30g of KOH with enough methanol to make a total solution volume of 100mL. This would result in a solution where 30% of the total weight comes from KOH. Be cautious when handling KOH as it is a caustic substance and should be handled with appropriate precautions.
A certain pain reliever was analyzed for aspirin by dissolving 250 mg of the tablet in water and titrating with .0300M KOH Titration required 29.40 mL of base What is percentage by weight of aspirin?
HC9H7O4+KOH--> [C9H7O4]-K+ +H2O moles of KOH= 0.300mol/L x 0.0294L =8.82x10^-4 mol KOH 1 mole of KOH=1 mole of HC9H7O4 moles of HC9H7O4= 8.82x10^-4 mol mass of aspirin= 8.82x10^-4 mol x 180.09 g/mol = 0.15884 g 250mg=0.25g %weight= (weight of solute/weight of sample) x 100% = ( 0.15884g/0.25g) x 100% =63.54% of aspirin
What student pronunciation in Japanese?
Here is "koko." It's pronounced: koh-koh.
How do you prepare 1N alcoholic koh solution?
To prepare a 1N alcoholic KOH solution, you will need to dissolve the appropriate amount of potassium hydroxide (KOH) pellets in a specific volume of anhydrous ethanol. First, calculate the molecular weight of KOH (39.10 g/mol) and then measure out the required weight to make a 1N solution. Once weighed, slowly add the KOH pellets into the anhydrous ethanol while stirring until fully dissolved. Check the final volume to ensure it reaches 1N concentration. Remember to handle KOH with care as it is caustic and generate heat when dissolving in ethanol.
What is the Italian translation of 'comfortable'?
Comodo is an Italian equivalent of the English word "comfortable."Specifically, the Italian word is the masculine form of an adjective. The pronunciation is "KOH-moh-doh." The feminine form, comoda, is pronounced "KOH-moh-dah."
