How many #"g"# of water are required to be mixed with #"11.75 g"# of #HgCl# in order to make a #"0.01 m"# solution? How would you prepare 250. mL of a 0.175 M solution of Cobalt (II) Chloride from the …

4 ⋅ 12.01 = 48.04 g We now know that one mole of carbon contains 48.04 grams of carbon. Next, we determine how many grams of carbon are in one mole of CO. 1 ⋅ 12.01 = 12.01 g Now, we know that …

65.0 "g N"_2 Any time you want to convert between moles and grams of a substance, you must know that substance's molar mass, which is the mass of one mole of that substance. (One mole is equal to …

Oct 2, 2017 · Avogadro's number shows the number of particles (atoms, ions etc.) in a mole of matter, while the molar mass shows the mass of 1 mole of a substance (in kg or g). If we divide the two …
