Answer: 0.62 M
Step-by-step explanation:
molarity = (moles of solute)/(liters of solution)
- If we approximate the atomic mass of Na to be 23 g/mol and the mass of Cl to be 35.5 g/mol, then the formula mass of NaCl is 58.5 g/mol.
- This means that 32 grams of NaCl is about 32/58.5 = 0.547 mol.
Hence, the molarity is (0.547)/(.88) = 0.62 M (to 2 s.f.)
