Q
Q: A solution has a concentration of 0.1 M NaCl. How many grams of NaCl are present in 1 liter of this solution? (Molar mass of NaCl = 58.5 g/mol)
Solution:
Mass = moles x molar mass = 0.1 moles x 58.5 g/mol = 5.85 g.
Steps: 6
Show Steps
Step 1: Understand that the concentration of the solution is 0.1 M, which means there are 0.1 moles of NaCl in 1 liter of solution.
Step 2: Know the molar mass of NaCl is 58.5 g/mol. This means 1 mole of NaCl weighs 58.5 grams.
Step 3: Calculate the mass of NaCl in grams using the formula: Mass = moles x molar mass.
Step 4: Substitute the values into the formula: Mass = 0.1 moles x 58.5 g/mol.
Step 5: Perform the multiplication: 0.1 x 58.5 = 5.85 grams.
Step 6: Conclude that there are 5.85 grams of NaCl in 1 liter of the solution.
