If 100g of NaCl is dissolved in 1500ml of water, what is the molarity?

To calculate the molarity of the solution, first, you need to determine the number of moles of NaCl dissolved in the water. Molarity is defined as the number of moles of solute per liter of solution.

1. Calculate the number of moles of NaCl:
   • The molar mass of sodium chloride (NaCl) is approximately 58.44 g/mol.

• To find the number of moles in 100 grams, you can use the formula:

[ \text{Moles of NaCl} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} ]

[ \text{Moles of NaCl} = \frac{100 \text{ g}}{58.44 \text{ g/mol}} \approx 1.71 \text{ moles} ]

2. Calculate the volume of water in liters:

   • The volume of water is given as 1500 mL, which is equivalent to 1.5 L.

3. Finally, calculate the molarity:

   • The formula for molarity (M) is:

[ M = \frac{\text{moles of sol
