Find the molarity of a 450 mL solution containing 13.7 g of ZnSO4.

The molarity is 0.189

Explanation:

Molarity is a measure of concentration of a solution that indicates the number of moles of solute that are dissolved in a given volume. In other words, the molarity indicates the amount of moles of solute that appear dissolved in each liter of the mixture.

Molarity is determined by the expression:

Molarity is expressed in units ().

So, you need to know the amount of moles of ZnSO₄. Then you must know the molar mass. If:

the molar mass of ZnSO₄ is:

ZnSO₄= 65 g/mol + 32 g/mol + 4* 16 g/mol= 161 g/mol

Then you can apply a rule of three as follows: if 161 g of ZnSO₄ is contained in 1 mole, 13.7 g in how many moles are they?

moles=0.085

Then you know:

Replacing in the definition of molarity:

Molarity=0.189

The molarity is 0.189

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.
