He massa molare

WebIn one molecule of glucose, there are 12 hydrogen, 6 carbon, and 6 oxygen atoms. So, altogether, the molar mass of a single molecule of glucose is equal to: 1.0079 (12)+12.0107 (6)+15.9994 (6) = 180.16 g/mol. Glucose has a molar mass of 180.16 g/mol. One mole of glucose molecule has a mass of 180.16 g. WebSolution Step 1: Molar mass: The mass of 1 mole of a substance is called its molar mass. Step 2: Formula for molar mass Molar mass = The atomic mass of element × number of …
