After the revision of the International System of Units (SI), the mole (the SI unit of amount of substance) is based on a fixed number of specified entities. This number is the fixed numerical value of the Avogadro constant N-A. Experiments for the practical realization of the mole on a...
In chemistry, the information being processed is seldom expressed in the units needed in the final result. In order to show the outcome in the proper units of measure, set up a unit conversion problem. This type of problem allows you to translate one size measure to another. For example, ...

Science Chemistry Dimensional analysis There are 1,000 grams in a kilogram. How many grams is 2.25 kilograms?Question:There are 1,000 grams in a kilogram. How many grams is 2.25 kilograms?Conversion of Units:Changes from one unit to another of a given measurement are referring...
Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species, such as electrons or ions like H+. The equivalent defines how many electrons or ions may be transferred in a chemical reaction. For example, in the aci
Which doesn't make any sense to me at all. And then my teacher said something like I had the general IDEA of how to answer the problem (which I totally don't) but that he insisted I write out the problem so the units work out. Which, I don't really know how to do. I understa...
Hint :There are many units in physical world such as kilometres (km), meters (m), centimetre (cm), millimetre (mm), nanometre (nm), and decametre (dm). To answer this question you should have the proper knowledge of conversions. The one conversion from one of them is been discussed ...
Understanding the conversion rates between different units of measurement can allow for quick calculations. See this demonstrated through the example of converting ounces to gallons. Ounces to Gallons Say a farmer in the US measures his cows' milk production by the ounce but sells it by the gallon...
