A mass of 0.630 g of NaCl is dissolved in in 525 g of water.
1. Calculate the molality of the salt solution.
2. Calculate the mole fraction of salt in this solution.
3. Calculate the concentration of the salt solution in percent by mass
4. Calculate the concentration of the salt solution in parts per million
i know it's easy but i have been using the equations and have been getting the wrong answers. can someone who understands, please help me out. thank you
