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.
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
Potassium is measured in what units?
Potassium levels in humans are measured in a unit known as milliEquivalents per Liter or (mEq/L).
How do you prepare0.1N KSCN soln?
58.08 (SCN-) + 39.10 (K+) = 97.18 gram/mol KSCN0.1 N = 0.1 M = 0.1 (mol/L) * 97.18 (g/mol) = 9.718 g KSCN per litre.
How do I convert 10 percent CO2 to parts per million CO2?
-- Take the number of percent. -- Multiply it by 10,000-- The answer is the number of parts per million. . 10 percent = 100,000 parts per million.
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.

How much does 50 percent potassium hydroxide weigh per gallon?
39.0983 ± 0.0001 u
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.

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).
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%)
Potassium mangnate to potassium per mangnate?
2K2MnO4 + Br2 ----> 2KMnO4 + 2KBr
Is corn high in potassium?
Corn is in the moderate potassium chart per cup its 100to200 mg
What is the formula for potassium per chlorate?
KMnO4.
Which has more potassium bananas or watermelon?
Per unit of weight, bananas have three times as much potassium.
Why is each statement reasonable 10 percent of 100 is 10 So 15 percent of 100 is 15?
Because the word "percent" derives from per + cent= per 100.Because the word "percent" derives from per + cent = per 100.Because the word "percent" derives from per + cent = per 100.Because the word "percent" derives from per + cent = per 100.
