Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
3) Weighted Average for All Atoms of an Element The atomic mass of an element is a weighted average of all the element's isotopes based on their natural abundance. It is simple to calculate the atomic mass of an element with these steps. Typically, in these problems, you are provided wit...
Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a

I know how to calculate the amount of atoms if I am given the amount of grams of the element at hand. Here is an example:How many atoms are in 22 grams of sulfur?But in the question that I have been presented, the only information I have is the following:Calculate the amount of at...
Atomic Mass Atoms are so small, it is difficult to discuss how much they weigh in grams. Use atomic mass units. an atomic mass unit (amu) is o
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
H2O = 2 + 16 = 18 g/mol (look at the subscript to note there are 2 hydrogen atoms) Use this value to convert the total number of grams of water into moles: (1 mol / 18 g ) * 100 g = 5.56 moles of water Now you have the information needed to calculate mole fraction. ...
Atomic weight is a fundamental concept in chemistry. Most chemical reactions are affected by the numerical relationships between atoms. However, when chemists need to measure reactants and products, they do not count individual atoms. Rather, they calculate atomic weights to guide their decisions. ...
In chemistry, a mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of a substance that contains the same number of particles (atoms, molecules, or ions) as there are in 12 grams of carbon-12. How is the number of ...
