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
