Achemist prepares a solution of sodium nitrate (nano3) by measuring out 122.g of sodium nitrate into 250.ml volumetric flask and filling the flask to the mark with water. calculate the concentration in mol/l of the chemist's sodium nitrate solution. round your answer to 3 significant digits.

The concentration of the sodium nitrate solution has been 5.72 mol/L.

The concentration has been defined as the proportion of the solute to the solvent. The concentration with presence of 1 mole of solute in a liter of solution has been given by molarity.

The molarity of the solution has been given by:

The mass of sodium nitrate in the solution has been 122 g.

The molar mass of sample has been 85 g/mol

The volume of the solution has been 250 ml.

Substituting the values for Molarity of the solution as:

The concentration of the sodium nitrate solution has been 5.72 mol/L.

[NaNO₃] = 5.72 M

Explanation:

Molarity is a sort of concentration.

It says the moles of solute, that are contained in 1L of solution.

The volume is in mL, so let's convert to L.

250 mL . 1 L / 1000 mL = 0.250 L

Let's convert now, the mass of NaNO₃, our solute into moles

122 g / 85 g/mol = 1.43 moles

Molarity = mol / L → 1.43 mol / 0.250L = 5.72 M

stupid i wont let you get a chance

explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
