Lelu [443]

To determine the shapes of molecules, we must become acquainted with the Lewis electron dot structure. Although the Lewis theory does not determine the shapes of molecules, it is the first step in predicting shapes of molecules. The Lewis structure helps us identify the bond pairs and the lone pairs.

Ammonium chloride is used as an expectorant in cough medicine. It has a density of 1.53 g/cm^3. What is the mass of 26.0L of thi
Katena32 [7]

Answer:

                     39.78 Kg

Explanation:

Data Given;

                  Density  =  1.53 g/cm³

                  Mass  =  <u>??</u>

                  Volume  =  26.0 L  =  26000 cm³

Formula Used;

                       The measure of mass per unit volume is called as density. It is a physical property of a substance and tells how tightly the particles are packed. Mathematically;

                  Density  =  Mass ÷ Volume

Solving for Mass,

                  Mass  =  Volume × Density

Putting values,

                  Mass  =  26000 cm³ × 1.53 g.mL⁻¹

                  Mass  =  39780 g  or   39.78 Kg
