Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between grams H2O and mole. 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.

The  Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen's is 16. In order to calculate the   27 Oct 2015 Explanation: One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms =  NCERT Textu al Exercise (Solved). 1. Calculate the molecular mass of the following : (i) H2O; (ii) CO2; (iii) CH4. Ans. (i) Molecular mass of H2O = 2 (1.008 amu)  For example, the mean molecular weight of water is 18.015 atomic mass units ( amu), so one mole of water weight 18.015 grams. Key Terms.
