What is the molarity of a solution in which 58.5 grams of nacl are dissolved in 1.0 l of solution?

Molarity = 1 M

Explanation:

Data given

mass of Nacl = 58.5 g

Volume of solution = 1 L

Solution:

To find the Molarity we have following formula

      Molarity = no. of moles of solute / 1 L of solution. . . . . . . . . (1)

Now

First we have to find number of moles of NaCl

Formula Used

                     No. of moles = Mass in g /molar mass . . . . . . . . . . . (2)

Molar mass of NaCl = 23 + 35.5

Molar mass of NaCl = 58.5 g/mol

Put values in equation 2

                      No. of moles = 58.5 g / 58.5 g/mol

                      No. of moles = 1 mol

Now,

Put values in equation 1

               Molarity = 1 mol  / 1 L of solution

               Molarity = 1 M

So,

The molarity of 58.5 grams of NaCl in 1.0 L of solution is 1.

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.
