What else can I help you with?
If you have 1911.9 g of a bleach solution. The percent by mass of the solute sodium hypochlorite NaOCl is 3.62. How many grams of NaOCl are in the solution I REALLY NEED HELP!!!!?
3.62 percent by mass means that there are 3.62 g NaOCl per every 100 g of solution. So, to find grams in 1911.9 g solution, just multiply ...3.62 g NaOCl/100 g soln x 1911.9 g soln = 69.2 g NaOCl
How many atom of oxygen are in 17.7g of potassium promangenate?
Assuming that the questioner meant to write "permanganate" instead of "promangenate", the answer may be found as follows: The formula of potassium permanganate is KMnO4, showing four atoms of oxygen per formula unit. The formula unit mass of KMnO4 is 158.03; therefore, 17.7 g of potassium permanganate contains [4(17.7)/158.03](Avogadro's Number) or 2.70 X 1023 atoms of oxygen, to the justified number of significant digits.
Potassium is measured in what units?
Potassium is typically measured in millimoles per liter (mmol/L) in the blood or urine. Potassium levels are important for proper muscle and nerve function, and abnormal levels can lead to health issues.
How much potassium in in Losartan potassium I am taking potassium and now Losartan potassium?
Losartan potassium contains approximately 85 milligrams of potassium per 100 milligrams of the medication. However, the actual amount of potassium you receive can vary based on the dosage of Losartan prescribed. It's important to consult with your healthcare provider about your potassium intake, especially if you are taking additional potassium supplements, to avoid potential complications.
How do you prepare0.1N KSCN soln?
To prepare a 0.1N potassium thiocyanate (KSCN) solution, dissolve 2.01 grams of KSCN in distilled water and dilute to 1 liter. Be sure to use a volumetric flask for accuracy and precision in preparing the solution.
When you put potassium per magnate into water it changes to what color?
When you put potassium permanganate into water, it changes to a deep purple or violet color.
Which compound give brown precipitate with alkaline potassium per mangnate solution?
Ferrous chloride in presence of hydrochloric acid gives brown precipitates of Ferric chloride with potassium permanganate.
What will happen if toluene react with potassium per magnate in presence of sodium carbonate?
When toluene reacts with potassium permanganate in the presence of sodium carbonate, the permanganate will oxidize the toluene to form benzoic acid. The sodium carbonate will help neutralize any acidic byproducts formed during the reaction.
How much 7 percent NaCl soln and 45 percent Nacl sol req'd to make 800ml 15 percent NaCl soln?
Only possible to calculate approximately (without knowing densities of all solutions) when 'percent' means 'gram per 100 ml' or 'ml per 100 ml'Solve the following equations to find V1 and V2:7% * V1 (ml) + 45% * V2 (ml) = 15% * 800 (ml)V1 (ml) + V2 (ml) = 800 (ml) [Especially this 2nd equation in an approximation]Outcome: 632 and 168 ml respectively, but this is an approximation! (due to the ignoring of volume contraction: mixing will result in LESS ml's than 800 ml, so concentration will be more than 15%)
Calculate the molarity of a solution of potassium permanganate and density is 1.04 gmL which contans 15.00 percent by mass?
C [mol/L] = w% * rho [g/mL] *1000 [mL/L] / (100% * M [g/mol] ) = = w% * rho [g/mL] *10 [mL/L%] / ( M [g/mol] ) = = 15.00 % * 1.04 [g/mL] *10 [mL/L%] / ( 158.034 [g/mol] ) = = 0.987 [mol/L] the molarity of the solution of potassium [in mol per liter] equals the content of KMnO4 by mass in percents multiply by density in g/mL multiply by 10 [mL/(L*%)] divide by molar mass of KMnO4 (M = 158.034 g/mol) This gives 0.987 mol/L. Thus the molarity equals approximately 1 M.
How much does 50 percent potassium hydroxide weigh per gallon?
The weight of 50% potassium hydroxide per gallon is approximately 10.49 pounds.
Fumigation methods for neonatral incubator?
Fumigation is usually done with formaldehyde gas using 40 ml of 40 per cent commercial formalin and 20 g of potassium permanganate for each 2á8 m3 of space inside the incubator or hatcher. Potassium permanganate may be placed in a glass or earthenware container and formalin poured over it. Fumigation should preferably be done-at the end of the working day and then the rooms closed.
If you have 1911.9 g of a bleach solution. The percent by mass of the solute sodium hypochlorite NaOCl is 3.62. How many grams of NaOCl are in the solution I REALLY NEED HELP!!!!?
3.62 percent by mass means that there are 3.62 g NaOCl per every 100 g of solution. So, to find grams in 1911.9 g solution, just multiply ...3.62 g NaOCl/100 g soln x 1911.9 g soln = 69.2 g NaOCl
Compute the rate of diffusion of the potassium permanganate in millimeters per minute (mmmin) and record.?
To compute the rate of diffusion of potassium permanganate, measure the distance it travels in a given time period. For example, if it travels 2 mm in 10 minutes, the rate of diffusion would be calculated as 2 mm / 10 min = 0.2 mm/min. Record this value as the diffusion rate. Adjust the measurements based on the actual distance and time observed in your experiment.
Weight of 6 percent KCL Pounds Per gallon?
The weight of 6% KCl (potassium chloride) solution is 6 pounds per gallon. This means that in one gallon of the solution, 6% of the weight is potassium chloride, which amounts to 6 pounds.
How many atom of oxygen are in 17.7g of potassium promangenate?
Assuming that the questioner meant to write "permanganate" instead of "promangenate", the answer may be found as follows: The formula of potassium permanganate is KMnO4, showing four atoms of oxygen per formula unit.

What is the cost of potassium?
In late 2008, bulk potassium was about $ 40 USD per pound.The price for the salt "potassium chloride" was only about 1% of that price, but sharply higher in 2009 (around $ 10 USD per pound in bulk).
