A student massed an unknown sample and found it to be 23.5g. The volume of the sample is 2.00mL. Calculate the density

The density of the sample is 11.8 g/mL.

Explanation:

We are given an unknown sample with a mass of 23.5 g and a volume of 2.00 mL and we want to determine its density.

Recall that density is given by:

Where ρ is the density, m is the mass, and V is the volume.

Substitute 23.5 g for m and 2.00 mL for V and evaluate:

Hence, the density of the sample is 11.8 g/mL.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
