moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles Using Avogrado's Number 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 wat...
If one mole each of CH_4, NH_3, H_2S, and CO_2 is added to 1 liter of water in a flask (1 liter of water = 55.5 moles of H_2O), how many moles of hydrogen, carbon, oxygen, nitrogen, and sulfur are in the flask? Round your answers to the nearest whole numb ...
moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles Using Avogadro’s Number We can use Avogadro’s number to determine the number of molecules in a drop of water. Avogadro’s number tells us that there are 6.022 x 10^23 mol...
