Answer :
Answer:
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
