WebAnd then we have oxygen right here, which is also closest to me. Arm eso oxygen needs to gain two electrons and in order to get to the electronic configuration of neon, so oxygen's going tohave a minus to charge. So we have in a plus and oh, minus two. I'm so in order to have our positive charges balancing our negative charges, we need two of them. WebLithium has a molar mass of 6.94 g/mol. 34.0 g of lithium may be converted to moles using the formula below: ... 3.330 mol/3.330 mol is equal to one mole of oxygen. Hence, CH2O is the empirical formula. Calculating the molecular mass of CH2O is necessary to get the molecular formula:
