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
