Which has more number of atoms 1g of Na or 1g of MG? No. of moles in Na=1/11 and in Mg = 1/12. Therefore no. of atoms is more in Na than Mg.How many atoms are there in 56g of Fe? This number, which represents the number of water molecules in 18g of water, or the ...
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...

To answer the question, we need to identify the term that describes the number of moles of an acid or base that can be added to one liter of a buffer solution to change its pH by one unit.1. Understanding Buffer Solutions:
moles of water = molecules of water / Avogadro's number moles of water = 3.35 x 1022/ 6.02 x 1023 moles of water = 0.556 x 10-1or 0.056 moles in 1 gram of water
