Question 39 of 42 Submit A particular vitamin's chemical formula has one cobalt atom. What is the molar mass of the vitamin if it contains 4.34% cobalt? g/mol 3 X 7 8 9 +/- x 100 Tap here or pull up for additional resources

Answer 1

is M g/mol Vitamin NA atom Answer (39) Let's assume molar mass of vitamin 1 molecule of vitamin contains 1 Cobalt at 1 mol of vitamin contains 1 mol of cobalt Molar mass of cobalt = 58.939/mo Sog M g of vitamin contain 58.93 g of cobal 58.93×100 g of co og of cobalt ... 100 g " M (1.34% means 100 g of Vitamin 58.93 x 100 = 4.34 has 4.34g of Henceg cobalt). N = 1.36x 103 So molar mass of vitamin is 1.36x103 g/mol
