Here’s an interesting thing about moles: 1 mole of any element or chemical is always the same number. For instance, 1 mole of hydrogen and 1 mole of oxygen both contain approximately 6.022 x 1023atoms. The respective masses of hydrogen and oxygen, however, are different. The same applies ...
You therefore need to know the mass in grams of a mole of cholesterol. This quantity is also known as the molecular weight of cholesterol. You can find the molecular weight of cholesterol by taking the sum of the atomic masses of the atoms in a molecule of cholesterol (which has a ...
or the molarity. A mole is a term which stands for 6.02 x 10^23 atoms or molecules of chemical. Another less common unit of concentration is molality. Molaility is the moles chemical per kilogram of solvent used in making the solution. You can convert from molarity to molality if you kno...
Typically, a semiconductor is made of a poor conductor, such as silicon, that has had impurities (atoms of another material) added to it. The process of adding impurities is called doping. In pure silicon, all of the silicon atoms bond perfectly to their neighbors, leaving no free electrons...
But when an X-ray hits an atom, it can knock electrons off the atom to create an ion, an electrically charged atom. Free electrons then collide with other atoms to create more ions. An ion's electrical charge can lead to unnatural chemical reactions inside cells. Among other things, the...
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 ...
Space farming has led to some other surprising and useful applications here on Earth. One is a special device called Bio-KES which converts ethylene into carbon dioxide and water using ultraviolet light. Ethylene causes plants to ripen and eventually spoil. A device like Bio-KES, used in food...
