If a saline solution has a concentration of 0.25 g per mL, calculate the following.
a) The concentration of this solution in %w/v.
b) The concentration of this solution in grams per litre (g/L).
c) The concentration of this solution in milligrams per mL (mg/mL).

  • chemistry -

    %w/v means g/100 mL soln.
    0.25g/mL x 100 mL = 25g = 25/100 mL = 25%

    I can't believe you can't do b and c. What exactly do you not understand about them.
