Calculate the molar mass of water

WebAnswer (1 of 6): The molar mass of hydrogen is 1.00794 g/mol. The molar mass of oxygen is 15.9994 g/mol. Given that the formula for water is H_{2}O, the molar mass would be 2(1.00794) + 15.9994 or 18.01528 g/mol. WebWater weighs about 18 g/mol, which is less than 29, so adding water vapor to air actually decreases the density. The amount that the density (or molar mass, if you like) decreases depends on the change in the absolute humidity--you can't calculate based on relative humidity alone without knowing the temperature. If the temperature and relative humidity …
