How many protons are in an isotope of sodium with a mass number of 25? What is the mass number of the hydrogen isotope that contains 2 neutrons? How can you find atomic number from mass number? How do you calculate atomic mass from atomic number?
For instance, calculate the mass percent concentration for the solution obtained by dissolving 10 g of sodium chloride (NaCl) and 6 g of sodium bicarbonate (NaHCO3) in 120 g of water. Add up the mass of all compounds in the solution, including the solvent, to calculate the total mass of...
Formula weight, in turn, represents the sum of the atomic weights, as found on the periodic table of the elements, of all of the atoms in the formula. Table salt, also known as sodium chloride or NaCl, for example, exhibits a formula weight of 58.44, which means that 58.44 grams of ...
The molar mass, or sometimes called atomic mass or molecular weight, is defined to be the mass of a particular element or compound over 1 mole of the substance. It can be obtained from this definition or by taking the sum of the mass of atoms composing a compound. Molar mass is ...
There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise...

All aluminum that you find in nature is called aluminum-27. The "27" is the atomic mass number, or the sum of the number of neutrons and protons in the nucleus. If you take an atom of aluminum and put it in a bottle and come back in several million years, it will still be an ...
Each element in the periodic table has its own unique energy pattern that relates to its physical and chemical properties, and many of Lee's poems are whip-smart allusions to how each element behaves in nature. Like this semi-sweet take on how sodium works in our nervous system: Sodium, ...

Hsp90 is an essential molecular chaperone responsible for the folding and activation of hundreds of ‘client’ proteins, including the glucocorticoid receptor (GR). Previously, we revealed that Hsp70 and Hsp90 remodel the conformation of GR to regulate l
