Answer:
The density of aluminum is 2.7 g/cm³. Thus given sample is aluminum.
Explanation:
Given data:
Mass of sample = 54 g
Volume of sample = 20 cm³
Density of sample = ?
Is the sample is aluminum = ?
Solution:
We will calculate the density from given mass and volume.
d = m/v
d = density
m = mass
v = volume
d = 54 g/ 20cm³
d = 2.7 g/cm³
From literature it is known that the density of aluminum is 2.7 g/cm³. Thus given sample is aluminum.
