Question

A block 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 1

Answer;

= 6.304 g/mL

Step-by-step 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
