Avogadroâ€™s number = 6.022 x 10²³ mol^-1

density of oleic acid = 895 kg/m³ = 895 g/L = 0.895 g/mL

Molar mass of oleic acid = 282 g/mol

Molar volume of oleic acid:

Molar volume = volume of 1 mol of substance

Hence,

Molar volume of oleic acid = molar mass/ density

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 282 g/mol / 895 g/L

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 0.315 L

Therefore,

Molar volume of oleic acid = 0.315 L

Formula to calculate percent error = I approximate value - exact value I / exact valueÂ Â x 100

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â (or)

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = I Experimental value - Theoretical value I / Theoretical valueÂ Â x 100
