1 mole=6.02*1023 molecules or atoms
5.23 moles=6.02*1023 * 5.23= {[(3.14846*1024molecules)]}
if you have a water sample that contains either nitrate chloride.
A soil sample contains living and nonliving materials. Which material was once living?

No, nitrogen is not present in starch. Starch is a carbohydrate and is composed of glucose molecules. Nitrogen is typically found in proteins, not carbohydrates.
On average, air contains around 76.7 % nitrogen gas by mass. This means that there is around 0.959 kg of nitrogen present.
1.51 x 10 ^23 molecules
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
if you have a water sample that contains either nitrate chloride.
150 (50 x 3)
by weighing out the bit of insulin that you want to find how much of it there is
contains the same number of molecules
if all the daughters have the same parents the logical answer is 2 parents making it appproximately 11.765% Or if the parents were not present in the sample O%
3.1 x 6.022 x10^23 =1.86682 x 10^24 of 3 methyl 2 butanol
Use a sample of pyrogallol (C6H6O6) in the sample followed by a combustion reaction. This compound absorbs oxygen present.
