Amino acids have a common structure where there is a carboxyl group at one end (CO2H) and a amino group at the other (NH2). There's also a side chain that's unique for every amino acid. When two amino acids are joined in producing a polypeptide, the carboxyl and amino groups are linked with the release of a water molecule.
So in this problem, you simply need to count the number of links, which will be 1 less than the number of amino acids in the chain. Hence, for a 14 amino acid chain, you need 13 links which produced 13 water molecules.</span>
The eletron pairs repel each other in a tetrahedral shape.
The tectonic plates drifting from each other caused the large landmass to separate.
Molar mass NaOH = 39.997 g/mol
number of moles:
n = mass of solute / molar mass
n = 10.0 / 39.997
n = 0.2500 moles
Therefore:
Molarity = moles of solute / volume ( L )
M = 0.2500 / 2.0
M = 0.13 mol/L
