Ablock of an unknown metal has a mass of 145 dg and a volume of 2.3 cm3. what is the density of the unknown in units of g/ml?

Answer;

  = 6.304 g/mL

Explanation;

Density = mass/volume

1 gram to 10 Decigram

mass = 145/10

         = 14.5 g

1 cm³ is equivalent to 1 mL

thus, 2.3 cm³ is equal to 2.3 mL

Density = 14.5 g / 2.3 mL

             = 6.304 g/mL
