So, to convert normality to molarity or vice-versa in the case of CaCl2, you know that a 1 M solution will generate a 2 M solution of chloride ions and a 1 M solution of Ca2+ions, which because of their charge also have a value of 2 for n. So in this case, N = (1 M)(2)...
If the molecular weight of a compound is 420 grams per mole, how many mg would you weigh out to make 100 mL of a 0.0200 M solution? How to calculate number of moles? How many kilograms are present in 43 moles of CF4? Convert each quantity to an amount in moles...
Chemical oxygen demand, or COD, is a test that measures the amount of organic compounds in water. More specifically, the test is a process of decomposing pollutants in water after two hours of boiling the water in a solution of potassium dichromate. If t

Convert the charges on the ions to coulombs by multiplying each charge by 1.9 x 10-19. The +2 calcium ion therefore exhibits a charge of 2 * 1.9 x 10-19= 3.8 x 10-19coulombs, and bromine exhibits a charge of 1.9 x 10-19coulombs. ...
When you encode your images in Base64, your images can be transferred and saved as text. Although there will be a 37% bloat in space requirements, it can be useful to encode images in Base64. For example with SAP HANA XS Advanced, you can quickly build a
Steps from Base64 to text ( confirmed in Linux ): Import base64 and codecs Convert the string to b"" using codecs.encode(...) and store it as a variable ( b64Str here ) Simply use base64.b64decode(b64Str) and store it as resStr ( Optional ) Print resStr And your code should...
5. Convert the PNG data you parsed into PostScript. 6. Add suitable image transforms. 7. Add to PostScript. Discovering the right point may not be simple. Working with JPEG is a bit simpler, since most JPEG files are directly compatible with ...
You are given a dosage of 30mg/kg to be given every twelve hours, how much is given (in grams) with each dose. Drug Dose: The dosage that is prescribed by the doctors for particular time duration is dependent on the body weight. The dosage ...
something must be compelling it to do so. This is called the oxidizing agent. For example, when iron rusts, oxygen is an oxidizing agent. The oxygen receives the electrons that the iron loses. The electrons that are lost in a reaction must be gained somewhere else in order to balance the...
