Metal mole fraction = 0.05; Mole fraction of citric acid: 0.19 & mole fraction of ethylene glycol : 0.76

Explanation:

Assuming the values given are their mole we can proceed in the following fashion for calculating molar ratio of each component to total number of moles of all components (mole fraction)

Mole of metal is = 1

Mole of Citric acid = 4

Mole of Ethylene glycol = 16

Calculate total constituent moles = 1+4+16 = 21

Mole fraction of metal in solution = 1/21 = 0.05

Mole fraction of citric acid = 4/21 = 0.19

Mole fraction of Ethylene glycol = 16/21 = 0.76

Sum of all components in solution = 0.05+0.19+0.76 = 1
