Answer:
1.282 M.
Explanation:
- Molarity is defined as the no. of moles o solute dissolved in a 1.0 L of the solution.
M = (no. of moles of solute) / (V of solution (L))
M = (mass/molar mass)of NaCl / (V of solution (L))
mass of NaCl = 41.2 g, molar mass of NaCl = 58.44 g/mol, V of solution = 550 mL = 0.55 L.
∴ M = (mass/molar mass)of NaCl / (V of solution (L)) = (41.2 g / 58.44 g/mol) / (0.55 L) = 1.282 M.
