explain how you determined the number of moles of cn in each compound
So you can use this to calculate the value of x and therefore the equilibrium concentrations of Fe3+ and SCN-. D) BaCl2, A:Option (C) Ca2F is incorrect. Atoms are so small, however, that even 500 atoms are too small to see or measure by most common techniques. Because the masses of individual atoms are so minuscule (on the order of 1023 g/atom), chemists do not measure the mass of individual atoms or molecules. For example, to convert moles of a substance to mass, we use the relationship, \( (moles)(molar \; mass) \rightarrow mass \tag{1.71} \), \( moles\left ( \dfrac{grams}{mole} \right ) = grams \), \( \left ( \dfrac{mass}{molar\; mass} \right )\rightarrow moles \tag{1.72}\), \( \left ( \dfrac{grams}{grams/mole} \right )=grams\left ( \dfrac{mole}{grams} \right )=moles \). = 65.38 grams 2) Calculate the number of moles of oxygen in the sample. A lack of this vita min in the diet can lead to anemia. What is the mass (in grams) of one molecule of cyanocobalamin? $('document').ready(function() {
