Ben has 1L of 0.1mol/dm3 solution of KI & wish to take a sample containing 8.3g of solute.What volume should he measure

  • chemistry -

    moles KI = grams KI/molar mass
    You have g KI and molar mass, solve for moles. Then M = moles/L soln. You know M and moles solve for L (Note: 0.1 mol/dm^3 = 1L)
