To find out the mass of the specified tin bar, we use the formula: mbr = ρо * Vbr, where ρо is the density of tin (const; according to the condition ρо = 7300 kg / m3); Vbr is the volume of the specified tin bar (Vbr = 20 cm3 = 2 * 10-5 m3).

Let’s calculate: mbr = ρo * Vbr = 7300 * 2 * 10-5 = 0.146 kg.

Answer: The mass of the indicated tin bar is 0.146 kg.
