Areaction requires 15.0 g of ammonium chloride. what volumeof a
14% solution of nh4cl which has a density of
1.04g/cm3 is needed to supply the 15.0 g
ofnh4cl?

103 cm³

Explanation:

A reaction requires 15.0 g of ammonium chloride. The percent by mass of ammonium chloride in the solution is 14%. The mass of the solution required is:

15.0 g ammonium chloride × (100 g solution/ 14 g ammonium chloride) = 107 g solution

The density of the solution is 1.04 g/cm³. The volume of solution corresponding to 107 g is:

107 g × (1 cm³/ 1.04 g) = 103 cm³

In 103 cm³ of a 14% solution, there will be 15.0 g of ammonium chloride.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
