What is the density of a solid with dimensions of 2.36 mm by 3.68 cm by 3.30 cm if has a mass of 2940 mg? Answer in g/cm^3

Explanation:

density = mass ÷ volume

            = 2.940 g ÷ (3.68 × 3.30 × 3.6) cm³

            =  0.067 g/cm³

since volume is the product of the dimensions;

1000 mg = 1 g;

10 mm = 1 cm

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
