1. The problem statement, all variables and given/known data How many grams of NaCl (molecular weight=58.5g mole^-1) would you dissolve in water to make a 0.5M NaCl solution with 500mL final volume? 2. Relevant equations 3. The attempt at a solutionSince, 1 L of 58.5g NaCl is equal 1M I used this to firstly convert 500ml into liters which is 0.5L and then I said that half 0f 58.5g is 27.25g NaCl and this will give me 0.5 M in 0.5L of water.
