Q
Q: If 1 mol of NaCl is dissolved in 1 kg of water, how many particles are present in solution?
Solution:
NaCl dissociates into 2 ions (Na+ and Cl-), so 1 mol of NaCl produces 2 mol of particles in solution.
Steps: 5
Show Steps
Step 1: Understand that 1 mol of NaCl means we have 1 mole of sodium chloride (NaCl).
Step 2: Know that when NaCl dissolves in water, it breaks apart into two different ions: sodium (Na+) and chloride (Cl-).
Step 3: Since 1 mol of NaCl produces 1 mol of Na+ ions and 1 mol of Cl- ions, we have a total of 2 moles of particles (1 mol Na+ + 1 mol Cl-).
Step 4: Remember that 1 mole of any substance contains approximately 6.022 x 10^23 particles (this number is called Avogadro's number).
Step 5: Calculate the total number of particles: 2 moles of particles x 6.022 x 10^23 particles/mole = 1.2044 x 10^24 particles.
