2.644 g of metal (M) was deposited when 8040 coulombs of electricity was passed through molten MF ₂ salt. What is the atomic mass of M ( F =96500 C mol ⁻¹ )
Options
- A63.47 u
- B65.54 u
- C31.74 u
- D61.48 u
Correct answer
A. 63.47 u
Step-by-step solution
M ²⁺+2 e ⁻ M 8040 coulombs deposited =2.644 ~g of metal aligned & 2 96500 coulombs will deposit = 2.644 8040 2 96500 & =63.46 ~g aligned Hence, atomic mass of metal is 63.46 ~g ~mol ⁻¹ .
