Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...
How many molecules of butane (C4H10) are contained in a 9.213-gram sample? How many hydrogen atoms are contained in this sample? How many atoms altogether are in C_4H_{10}? How many atoms of carbon are there in 0.125 mol of butane, C_4H_{10}? Consider a sample of 24.0...
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)=...

The Avogadro's number is the number of particles (molecules or atoms or ions or even photons) that are contained in one mole of a substance. It is equal to 6.023×1023particles per mole. Answer and Explanation: Here we are given the volum...
How many moles are in 16.48 g Mg? Answer in units of mole. Molar Mass: One mole is defined as {eq}\displaystyle 6.022\ \times\ 10^{23} {/eq} atoms or molecules. Now since one atom or molecule has a unique mass due to the atomic model, each measurement of one mole will have...

of each acid's molecule is described through a molecular formula. The molar mass of an acid in the literature refers to the total mass in grams for one mole (Avogadro's number) of its molecules. For example, the molar mass of hydrochloric acid (HCl, binary acid) is 36.45 g/mol. ...
How many moles of N2 are produced from 3.64 mol of NH3? How many moles of NH_3 can be produced from 16.5 mole of H_2 and excess N_2? How many moles of NH_3 can be produced from 15.0 mole of H_2 and excess N_2? How many molecules (not mo...
