Answer
the number of moles of Copper = 0.004187 mol
Chemical formula of Copper Gluconate is Cu(C6H11O7)2
Explanation
Each Copper gluconate has 1 Cu unit, as per the molecular formula Cu(C6H11Ox)n
x = 7
n = 2
Cu(C6H11O7)2
Hence, the number of moles of Copper gluconate = the number of moles of Copper
the number of moles of Copper Gluconate =
= 1.9 g/453.8 g/mol
the number of moles of Copper Gluconate = 0.004187 mol
the number of moles of Copper = 0.004187 mol
