1. A 751 mL NaCl solution is diluted to a volume of 1.06 L and a concentration of 8.00 M . What was the initial concentration? Express your answer with the appropriate units. 2. How many liters of a 3.18 M K2SO4 solution are needed to provide 98.8 g of K2SO4 (molar mass 174.01 g/mol)? Recall that M is equivalent to mol/L. Express your answer to three significant figures.
A 1.000 L solution contains 0.5844 g NaCl (molar mass 58.44 g/mol) and 7.455 g KCl (molar mass 74.55 g/mol), both strong electrolytes. The concentration of Cl− ions in this solution is (A) 0.1000 mol/L (B) 0.1100 mol/L (C) 0.2000 mol/L (D) 1.000 mol/L (E) 1.100 mol/L
If 0.80 L of a solution contains 4.3 g of KCl, what is its molar concentration?
A 115-ml sample of an 8.2 M NaCl solution is diluted to 3.0 L. What volume of the diluted solution contains 12.8 g of NaCl? (Hint: Figure out the concentration of the diluted solution first.) Express your answer using two significant figures. Please explain how you got the answer, thank you!
5 L of a salt water solution contains 120 g of NaCl. What is the molarity of this solution?
A 155-ml sample of an 8.0 M NaCl solution is diluted to 2.0 L . What volume of the diluted solution contains 10.8 g of NaCl? (Hint: Figure out the concentration of the diluted solution first.)
What volume in (L) of 12.0% NaCl solution is needed to provide 42.0 g of NaCl? Assume the density of the solution is 1.05g/mL.
