What is the molarity of a solution with 6 g of #NaOH# in enough water to make a 2 L solution?

Answer 1

#"Molarity"# #=# #"Moles of solute (moles)"/"Volume of solution (L) "#

Here, approx. #0.05*mol*L^-1#.

Consequently,

#"Concentration (NaOH)"# #=# #(6*g)/(58.44*g*mol^-1)xx1/(2*L)# #=# #??mol*L^-1#.

To find the molarity of the solution, first, calculate the number of moles of NaOH using its molar mass, then divide the moles by the volume of the solution in liters.

Molar mass of NaOH = 22.99 g/mol (Na) + 16.00 g/mol (O) + 1.01 g/mol (H) = 39.99 g/mol

Number of moles of NaOH = mass / molar mass = 6 g / 39.99 g/mol ≈ 0.150 mol

Molarity = moles of solute / volume of solution in liters = 0.150 mol / 2 L = 0.075 M

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
