KONSENTRASI LARUTAN

Molar consentration is amount of moles solute in1 liter solution. Formula of molar concentration is :

                                                   gr          1000   

            M =  mol/V       M = ----------- x -------------

                                                  Mr            vol

Problem :

1. Determine molar concentration of solution 2 mol NaOH in 100 mL water

2. Determine molar concentration of 6 gram urea solubled in water  so volume  250 mL.

3. Determine molar concentration of H2SO4 (p), if on the botle label

    writen that presentation H2SO4 is 96% and density of solution is  1,8 Kg/L.

4. Student will make 1 litre of ureum solution 1 M.How much mass of ureum

    needed.
