5.85gm of NaCl is dissolved in water and the solution is made up to 0.5 litre. what is the molarity of solution ????

Answer 1

From the periodic table, the molar weight of Na and Cl:
Na - 23
Cl - 35.45
Thus molar mass of NaCl is 58.45 g/mol

Molarity is moles solute over liters of solution.
To get the moles, we divide the given mass by the molar mass:
5.85 g NaCl / 58.45 g/mol = 0.10 mol NaCl

Thus,
M = 0.10 mol NaCl / 0.5 L
M = ?
