a)0.500 mol of NaOH in 1.05 L of

solution

b) 14.5 g of NaCL in 677 mL of solution

2) How many grams of solute are present in 455 mL of 0.680 M KBr?

3)78.0 mL of a 1.70 M solution is diluted to a total volume of 238 mL. A 119-mL portion of that solution is diluted by adding 109 mL of water. What is the final concentration? Assume the volumes are additive.
