10% (m/m) Sodium Hydroxide solution, NaOH(aq) is used to break down wood fibre to make paper.
A) What mass of the solute is needed to make 250mL of 10% (m/m) solution?
B) What mass of solvent is needed?
C) What is the molar concentration of the solution?

  • Chemistry -

    (g solute/250 g)*100 = 10%. Solve for g solute.

    250 g solution - 25 g solute = ?? g water.

    Convert g solute to moles, then M = moles/L.
