A piece of antimony with a mass of 17.41 g is submerged in 46.3 cm3 of water in a graduated cylinder. The water level increases

kobusy [5.1K]

Answer:

6.696 g/cm3

Explanation:

From the question;

Mass = 17.41g

Volume of water before = 46.3 cm3

Volume of water after = 48.9 cm3

Volume of antimony = Volume after - Volume before = 48.9 - 46.3 = 2.6 cm3

Density = Mass / Volume

Density = 17.41 / 2.6 = 6.696 g/cm3
