130.0 grams of NaNO 3 is dissolved in water to make a 5.00 L solution. What is the molarity of the solution? (Molar mass of NaNo3 =g/mol) what is the molarity

0.31M

Explanation:

Given parameters:

Mass of NaNO₃  = 130g

Volume of solution  = 5L

Molar mass  of NaNO₃  = 23 + 14 + 3(16) = 85g/mol

Unknown:

Molarity of solution = ?

Solution:

Molarity is one of the ways of expressing concentration.

It is defined as the number of moles in a volume of solution.

 Molarity  =

  let us find the number of moles of NaNO₃;

                Number of moles  =  =  = 1.53moles

Molarity  of solution =   = 0.31M

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
