Vitamin B12, cyanocobalamin, is essential for human nutrition.
Its molecular formula is C63H88CON14014P. A lack of this vitamin in the diet can lead to anemia. Cyanocobalamin is the form of the vitamin found in vitamin supplements.
What is the mass (in grams) of one molecule of cyanocobalamin?

That is, select Group 1 next to all the compounds with the first empirical formula. (If all four compounds have the same empirical formula, then they'll all end up in Group 1.) • Next, select Group 2 next to all the compounds with the second empirical formula. And so on. • If all four compounds have different empirical formulas, then they'll each end up alone in their own group: Compound A will be alone in Group 1, Compound B will be alone in Group 2, and so on. About the sketches: the lines stand for chemical bonds between the atoms. Just ignore the dots. They stand for "lone pairs," and you'll learn about them later.
