The maximum number of moles of In that could be deposited at the cathode is 0.02 mole.
Given data:
number of ions, n=+3 ions
charge passed through the electrolytes,
Q = 0.06 F.
3 ions = 3 F
3 F ----------------------- 1 mole of the ion
0.06 F ---------------------- ? mole of the ion
no of moles = 0.06 F×1 / 3 F
no of moles =0.02 moles

Answer:
d = 4.5 g/cm³
Metal cube is made up off titanium.
Explanation:
Given data:
Edge length of cube = a = 11.4 mm
Mass of metal cube = 6.67 g
Density and identity of metal = ?
Solution:
First of all we will calculate the volume of cube.
V = a³
V = (11.4mm)³
V = 1481.54 mm³
mm³ to cm³:
1481.54 mm³× 1 cm³/ 1000 mm³
1.482 cm³
Density:
d = m/v
d = 6.67 g/ 1.482 cm³
d = 4.5 g/cm³
Metal cube is made up off titanium because density of titanium is 4.5 g/cm³.
