372 ml is the volume of aluminum, density is 2.70 g/ml what is the mass in grams

930 g

Explanation:

D = m/V     Multiply both sides by V

m = VD

Data:

V = 372 cm³

D = 2.70 g/cm³

Calculation:

m = 372 × 2.50

m = 930 g

The mass of Al is 930 g.

a polar bond is formed when electrons are shared unevenly between atoms

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
