The invasive lionfish species, Pterois miles, has rapidly established new populations in the Eastern Mediterranean Sea, impacting local fish biodiversity. The molar mass of water is (1. From the periodic table we see the atomic weight of hydrogen is 1.01 g. Likewise, 1. 0. Note, ΔH f o =of liquid water is less than that of gaseous water, which makes sense as you need to add energy to liquid water to boil it. The latter amount is most convenient and would simply involve the use of molar masses instead of atomic and formula masses, as demonstrated Example 3. 1 mole is equal to 1 moles H2O, or 18. A certain reaction produces 86. The molar mass is defined as the mass in grams of 1 mol of that substance.
