To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that compound. The molar mass of elements tells you the molar mass of a compound, so you can figure this out. Molar Mass Definition The molar mass definition is the grams of a ...

To figure this out, you will need the molar mass of NaCl which is 58.44 g/mol. First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: \(\mathrm{2g\enspace NaCl\Biggl(\dfrac{1mol\enspace NaCl}{58.44g\enspace NaCl}\...

Carry out the following calculation, making sure that your answer has the correct number of significant figures: V = 4/3 pi r3, where r = 27.695 mm. (Answer in mm3) Perform the following calculations and convert your answers to proper scientific notation. (Round to two decimal place...
to find out how many g of helium you need to put into the balloon. After you get that number . .. you then multiply that number by Helium's molar mass to get the amount of moles of Helium you need . . . then take the amount of Helium and multiply by STP (22.4L) to find the...
Your dentist can figure out the cause and recommend the proper treatment.</p> <p><strong>You Have a Loose Dental Filling</strong></p> <p>Nowadays, dental fillings are quite strong. However, they can still endure wear and tear over time and become loose. If a dental filling has come ...
Oxidative cleavage of a glycosidic bond by an LPMO requires reduction of the catalytic mono-copper site, from the inactive [LPMO–Cu (II)] state to the active [LPMO–Cu (I)] state, by an electron donor, typically a small molecule reductant, such as ascorbate or gallic acid. The reduc...
000 meters. The water content is harder to figure out because it varies according to the densities of thedifferent types of clouds. On top of that, the temperature can change the mass of water. While it can vary, scientists follow a general consensus of water content per cubic meter for ...
