Question (1): We prepared a solution (103 * 2.013g) of ethylene glycol (HO) CH2 (2OH) to (103 * 2.01ml) from

water. If the degree of water density is equal to (0.9973 g / cm3), calculate / d:

A- The molar fraction of ethylene glycol, and b- molar concentration of ethylene glycol

Question (2): Nitric acid (HNO3) is available in the market as an aqueous solution with a concentration of (33.7) mol, and its clearance is (1.35 g / cm3).

The molar concentration of this solution
