Una disolución acuosa contiene el aminoácido glicina (NH2CH2COOH). Suponiendo que este aminoácido no ioniza, calcule la molalidad de la disolución si se congela a -1,1 °C. (agua:
constante crioscópica 1,86 °C/molal; punto de congelación 0 °C).

The missing component to the table to the right or indicated with orange letters complete the table by filling in the corresponding numbers or symbols
