It is possible for head lice to live temporarily on items such as bedding, couches, hair accessories, car seats, toys and clothing. Fortunately, head lice can only survive 24-48 hour off of the head and are relatively easy to remove from the home.
The molar mass of aspirin (2-acetoxybenzoic acid), C9H8O4, is 180.157 g/mol. The molar mass of aspirin (2-acetoxybenzoic acid), C9H8O4, is 180.157 g/mol.
Multiply the element's atomic mass by the molar mass constant by the number of atoms of that element in the compound. Here's how you do it: 1  For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.his converts atomic units to grams per mole, making the molar mass of hydrogen 1.007 grams per mole, of carbon 12.0107 grams per mole, of oxygen 15.9994 grams per mole and of chlorine 35.453 grams per mole. 3. Find the molar mass of a divalent molecule. Some elements are only found in molecules of 2 or more.
