Calculati masa de solutie de NaOH de concentratie 20% care reactioneaza cu 2 moli de aminoacid N-terminal ( acid glutamic)

Răspuns :

HOOC-CH2-CH2-CH(NH2)-COOH + 2NaOH = NaOOC-(CH2)2-CH(NH2)-COONa + +2H2O
nNaOH = 2n acid = 4 moli
solutia de NaOH :  md = 4x40 = 160g   c = 20%     ms = 160x100/20 = 800g
