An unknown material has a mass of 5 g and a volume of
7.25 cm3. what is the density of the material? round to the nearest tenth.

36.3

Explanation:

5 x 7.25 = 36.25

When you round this to the nearest tenth you will get 36.3

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
