Q
Q: If 50 grams of NaOH is dissolved in 1 liter of solution, what is the molarity? (Molar mass of NaOH = 40 g/mol)
Solution:
Moles of NaOH = 50 g / 40 g/mol = 1.25 moles. Molarity = 1.25 moles / 1 L = 1.25 M.
Steps: 7
Show Steps
Step 1: Identify the mass of NaOH you have, which is 50 grams.
Step 2: Find the molar mass of NaOH, which is given as 40 g/mol.
Step 3: Calculate the number of moles of NaOH using the formula: Moles = Mass (g) / Molar Mass (g/mol). So, Moles of NaOH = 50 g / 40 g/mol.
Step 4: Perform the calculation: 50 g / 40 g/mol = 1.25 moles.
Step 5: Identify the volume of the solution, which is 1 liter.
Step 6: Calculate the molarity using the formula: Molarity (M) = Moles of solute / Volume of solution (L). So, Molarity = 1.25 moles / 1 L.
Step 7: Perform the calculation: 1.25 moles / 1 L = 1.25 M.
