When 9.6 grams of NaBr are dissolved in enough water to create a 165-gram solution, what is the solution's concentration, expressed as a percent by mass?
4.8% NaBr
5.5% NaBr
5.8% NaBr
6.2% NaBr

  1. i got u

    165 g - 9.6 g = 155.4 g H2O = 155.4 ml
    9.6 g/155.4 ml x 100 ml = 6.18%
    Answer would be 6.2%

    im not a nerd cause that stupid
