Given the data from the question, the identity of the unknown metal having a of mass 133 g is Cobalt
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the density </h3>
- Mass = 133 g
- Volume of water = 25 mL
- Volume of water + metal = 40 mL
- Vol of metal = 40 – 25 = 15 mL
Density = mass / volume
Density = 133 / 15
Density = 8.86 g/mL
Comparing the density of the unknown metal (i.e 8.86 g/mL) with those given in the chart in the question above, we can conclude that the unknown metal is Cobalt
