Molarity Calculation Excitement!
What is the molarity of a solution containing 3.50 g of sodium chloride (NaCl) dissolved in 55.0 mL of water?
Final Answer:
The molarity of the NaCl solution is approximately 1.09M.
Let's dive into the exciting world of molarity calculations! When we have a sample of 3.50 g of sodium chloride (NaCl) that is dissolved in 55.0 mL of water, we can determine the molarity of the solution.
Molarity is a measure of the concentration of a solute in a solution, represented as moles of solute per liter of solution. To find the molarity in this scenario, we first need to convert the mass of NaCl to moles using the molar mass.
The molar mass of NaCl is approximately 58.44 g/mol. By using this molar mass, we can calculate that 3.50g of NaCl is equal to 0.0599 mol of NaCl.
Next, we convert the volume of the solution to liters by changing 55.0 mL to 0.055 L. Finally, we determine the molarity of the solution by dividing the moles of NaCl by the volume in liters, resulting in a molarity of approximately 1.09M.
So, there you have it! The molarity of the NaCl solution in this case is around 1.09M, adding a touch of excitement to chemistry calculations!
