60g/mol
The molar mass of acetic acid is 60,05 g.
Urea
0.01 molar
6.00ml * 1.08 = 6.48g Molar mass acetic anhydride = 102.09 g/mol 6.48g = 6.48/102.09 = 0.063moles.
Barfoed's reagent consists of a 0.33 molar solution of neutral copper acetate in 1% acetic acid solution
For acetic acid the molar and normal concentrations are identical.The value is 60,05 g/L.
The molar mass of acetic acid is 60,05 g.
The molar mass of ethanoic acid (acetic acid, C2H4O2) is 60.05 g mol−1H2CO3 molar mass 62.03 g mol-1HNO3 molar mass 63.01 g mol−1
Urea
Molar mass of ethanoic acid = (1x12) + (3x1) + (1x12) + (2x16) + (1x1) = 60 no. of moles = mass/ molar mass = 21.71/60 = 0.362 moles
0.01 molar

Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
ethanol has a higher boiling point- of 78°C :)
The mass of one mole of a substance is its molecular mass in grams. The molecular mass of acetic acid (CH3COOH) is: 12 + (3 x 1) + 12 + 16 + 16 + 1 = 60, therefore, 1 mole of acetic acid has a mass of 60g. (The numbers used in the calculation are the mass numbers of each element)
