1. 26.0 ml of a 1.0 m solution of nacl contains what mass of nacl?

1.519 g NaCl

Explanation:

The relationship between moles of a solute, volume of the solution and the concentration of the solution is given by;

Concentration =Moles ÷ Volume of the solution

Therefore, to get mass ,

Number of moles = Concentration × volume of the solution

In this case

we are given, Volume = 26.0 mL

Molarity or concentration = 1.0 M

We are required to determine the mass of the solute

Step 1: Calculate the number of moles of NaCl

Moles = Concentration × Volume

           = 1.0 M × 0.026 L

           = 0.026 Moles NaCl

Step 2: Calculate the mass of NaCl

Mass is given by;

Mass = Number of moles × Molar mass

Molar mass of NaCl = 58.44 g/mol

Therefore

 Mass      = 0.026 moles × 58.44 g/mol

                = 1.519 g

Therefore, the mass of NaCl is 1.519 g

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
