C. length and mass
D. solubility and mass
A sample of aluminum has a volume of 3.0 cm and a mass of 8.1 g. What is the density of
aluminum?
A. 2.7 g/cm
C. 11.1 cm
B. 5.1 g
D. 24.3 g/cm

Correct option is (A).

Explanation:

Given data:

Volume,

Mass,

The density of the aluminium can be given as,

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
