Using Avogadro's Number to Calculate the Number of Molecules Say you have 2 moles of NaCl. How many molecules of NaCl is that? Here's where you can use Avogadro's number: \(\mathrm{2mol\enspace NaCl\Biggl(\dfrac{6.022\times10^{23}\enspace molecules\enspace NaCl}{1mol}\Biggr)=...
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....

Roughly, for every NADH that enters the electron transport chain three ATP molecules are generated, while two are generated for every FAHD2 that enters the electron transport chain. Calculate how many ATP are generated during the breakdown of one glucose ...
How many moles are in 14.3g of C6H6 ? Calculate the mass of 3.22×1022 molecules of SiH4.There are 2 steps to solve this one. Solution Share Step 1 Here, it needs to determine the mole of C6H6 and mass of SiH4. Given that, View the ful...
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. ...
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
