he shell of an egg from a chicken is mostly made of calciumcarbonate, lined with a semipermeable membrane. The shell of theegg can be dissolved using acetic acid (vinegar). The gas-evolvingreaction is as follows:
CaCO3(s)+2CH3COOH(aq) ---->Ca(CH3COO)2(aq)+H2O(l)+CO2(g)
Suppose you start with two fresh eggs, with the shell alreadydissolved. You place one egg in a solution of corn syrup (75% byweight sucrose [C12H22O11]; 25% water; density of 1.38g/mL) and theother in table salt solution (0.70 M NaCl). In both cases the eggshrivels, but which one will have the greater volume? Assume theeggs are the same size to start, that all solutions behaveidentically, and you must provide your answer mathematically andexplain. (Note: Assume 25 degrees C).
