A solution is prepared by dissolving 58.5 g of NaCl in 1 L of water. What is the concentration in terms of molarity? (Molar mass of NaCl = 58.5 g/mol)

Step 1: Identify the mass of NaCl you have, which is 58.5 grams.
Step 2: Find the molar mass of NaCl, which is given as 58.5 g/mol.
Step 3: Calculate the number of moles of NaCl using the formula: Moles = Mass (g) / Molar Mass (g/mol). So, Moles of NaCl = 58.5 g / 58.5 g/mol.
Step 4: Perform the calculation: 58.5 g / 58.5 g/mol = 1 mole of NaCl.
Step 5: Identify the volume of the solution, which is 1 liter (L).
Step 6: Calculate the molarity (M) using the formula: Molarity = Moles of solute / Volume of solution (L). So, Molarity = 1 mole / 1 L.
Step 7: Perform the calculation: 1 mole / 1 L = 1 M.

Molarity – Molarity is defined as the number of moles of solute per liter of solution.
Moles Calculation – Calculating moles involves dividing the mass of the solute by its molar mass.
