Answer:

58.45g

Explanation:

molar mass of chromium = 52g/mol

Q = it

i = 45.2amp

t = 2x60x60 = 7200sec

c = 3+

F = 96500

mass/molar mass = Q/CF

mass/52=(45.2x7200)/3x96500

mass/52 = (325440)/289500

mass/52 = 1.124

mass =52 x 1.124 = 58.45g

mass = 58.45g

Answer:

58.45g is the answer

Explanation:
