The molar mass of H2O (Water) is: 18.015 grams/mol. See also our theoretical yield calculator for chemical reactions (probably your next stop to finish the problem set).

Type in your own numbers in the form to convert the units! Mixing ethanol and water is exothermic, with up to 777 J/mol being released at 298 K. Mixtures of ethanol and water form an azeotrope at about 89 mole-% ethanol and 11 mole-% water or a mixture of 95.6 percent ethanol by mass (or about 97% alcohol by volume) at normal pressure, which The specific heat capacity of liquid water is 4.186 J/gm K. This means that each gram of liquid water requires 4.186 Joules of heat energy to raise its temperature by one degree Kelvin. One molar mass of water is equivalent to 18 grams. Therefore, the molar heat capacity becomes the product of 4.186 and 18.
