A 5.46 %w/v solution (5.46g per 100.0 mL) of starch in water was
found to have an osmotic pressure of 84.9 mmHg at 300.6 kelvin.
Calculate the average molar mass of the starch used, taking 1.00
atm = 760.0 mmHg. The value of the gas constant, R , is 0.0821 L
atm K-1 mol-1
Present your answer as a numerical value only, to 3
significant figures in the form x.xxEx.
