How many moles are in 119 grams of uranium
WebAll you need to do is correctly enter your formula, choose whether you want a conversion from grams to moles or a conversion from moles to grams, and, in case of g to mol, enter the mass, or, in case of mol to g, enter the moles. Grams to moles example problem. Problem: Convert 25.0 grams of KMnO4 to moles. Solution: WebThe question indicates that there is 1 mole of H2. Thus there are 6.022 * 1023molecules of H2. However the question is asking for the amount of atoms in 1 mole of H2. Thus we must consider the makeup of an H2molecule, where we see that it is a diatomic molecule.
