How many moles are present in 180 g of h2o
Web10 feb. 2024 · For example, the molar mass of water (H 2 O) is 18.02 grams per mol. This means there are 18.02 grams of water in one mol of water. How Do You Convert From Grams to Molecules? Given the different conversion factors mentioned above, there is enough information to convert from grams to molecules. WebExample 1: Let's determine the mass of 1 dozen eggs. 1 egg mass = 60g and 1 dozen = 12. Therefore, 1 dozen of egg masses = 1 dozen of 60g = 12 of 60g = 12 x 60g = 720g Example 2: Show that 1 mole of 12C is 12g. Recall that, 1 amu = 1.6605 x 10^ (-27) kg and 1 mole = 6.02 x 10^23. 12C = 12 amu Therefore, 1 mole of 12C = 1 mole of 12 amu
