1. Calculate the moles of NaCl:
* Molar mass of NaCl: 58.44 g/mol
* Moles of NaCl: (1.00 g NaCl) / (58.44 g/mol) = 0.0171 mol NaCl
2. Calculate the volume of solution:
* Molarity (M): 0.171 mol/L
* Volume (L): (0.0171 mol NaCl) / (0.171 mol/L) = 0.1 L
* Volume (mL): 0.1 L * 1000 mL/L = 100 mL
Therefore, you would need 100 mL of water to make a 0.171 M solution containing 1.00 g of NaCl.
Important Note: This calculation assumes that the volume of the NaCl is negligible compared to the volume of water. In reality, adding the NaCl will slightly increase the total volume of the solution. For very concentrated solutions, this difference could be significant, but for this specific case, the assumption is reasonable.
