If a current of 2.5A flows through an electrolyte for 3 hours and 1.8g of a substance is deposited, what is the mass of the substance that will be deposited if a current of 4A flows through it for 4.8 hours?
2.4g
3.2g
4.6g
4.8g
Correct answer is C
First let's find z
z = MIt
z = 1.82.5×(3×60×60)
Therefore, the new M equals
M = zIt
M = 1.8×4×4.8×60×602.5×3×60×60
M = 4.6g
