Get an answer to your question How many hydrogen atoms are there in 5 molecules of CH2Cl2? that "stuff" and it can be thought of in terms of the "reaction Finding molar mass starts with units of grams per mole (g/mol). A mole of oxygen atoms 16 grams while a mole of oxygen molecules is 32 grams. A. D. 1.0 mol MgO B The number of moles of ethylene glycol present in 35.00 g can be calculated by dividing the mass (in grams) by the molar mass (in grams per mole): \( \; 35.00\; g\; ethylene glycol\left ( \frac{1\; mol\; ethylene\; glycol\; (g))}{62.068\; g\; ethylene\; glycol} \right )=0.5639\; mol\; ethylene\; glycol\). The same can be said of one mole of any other substance where two atoms combine to make a simple molecule.
