References Test 2 question Content Area One liter of solution is made by dissolving 21.7 g of NaCl in water. What is the molarity of the solution?
Accepted Answer
Here's how to calculate the molarity of the NaCl solution:
1. Find the moles of NaCl:
- Divide the mass of NaCl (21.7 g) by its molar mass (58.44 g/mol):
21.7 g / 58.44 g/mol = 0.371 mol NaCl
2. Calculate the molarity:
- Molarity (M) is defined as moles of solute per liter of solution:
M = moles of NaCl / liters of solution
M = 0.371 mol / 1 L = 0.371 M
Therefore, the molarity of the NaCl solution is 0.371 M.
