英语化学求摩尔质量!
Vitamin B12,cyanocobalamin,is essential for human nutrition.It is concentrated in animal tissue but not in higher plants.Although nutritional requirements for the vitamin are quite low,people who abstain completely from animal products may develop a deficiency anemia.Cyanocobalamin is the form used in vitamin supplements.It contains 4.34% cobalt by mass.Calculate the molar mass of cyanocobalamin,assuming that there is one atom of cobalt in every molecule of cyanocobalamin.
____________g/mol
