Approximately how many moles of al3+ are reduced when 0.1 faraday of charge passes through a cell during the production of al? (note: assume there is excess al3+ available and that al3+ is reduced to al metal only.)
a. 0.033 molb. 0.050 molc. 0.067 mold. 0.10 mol

The answer for #3 is c but i don't know why

What is another way to determine mass times acceleration?

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
