Answer:
15.1 g/mL
Explanation:
The density of a substance is defined as the ratio of the mass of the substance and the volume of the substance. Mathematically, it is expressed as:
Density = mass in grams/volume in mL
In this case, the mass of the metal = 30.2 g
Volume of the metal = volume of water displaced by the metal.
The volume of water displaced by the metal can be calculated as the final volume of water after placing the metal - initial volume of water before placing the metal.
Hence, volume of metal = 22.0 - 20.0 mL = 2.0 mL
Density of metal = 30.2/2.0 = 15.1 g/mL
The density of the metal is 15.1 g/mL
The identity of the metal is not in the table.
Answer:
not listed
Explanation:
when you are looking for any part of the denisty equation [tex]D = \frac{M}{V}[/tex] you can just plug in the numbers
In this case the M = 30.2 and the V = 2 (because the change in the volume is the volume of the item)
so to find the density it would be
[tex]D = \frac{30.2}{2}[/tex]
so then,
D would hahve to = 15.1
