Osmotic pressure in chemistry question?

What osmotic pressure (in atmospheres) would you expect for 72 mL of an aqueous solution containing 2.4g of sodium acetate (NaCH3CO2) at 16 degrees Celsius? I need to know how to set up the equation as well as finding the answer. Thank you.

    moles sodium acetate = 2.4 g / 82.03 g/mol=0.029

    M = 0.029 mol/ 0.072 L=0.40 M

    sodium acetate is a strong electrolyte for which i ( Vant'Hoff factor ) = 2

    osmotic pressure = 0.40 x 2 x 0.08206 x 289 K= 19 atm
