An aluminum plant produces 60 million kg of aluminum per year. It takes 17 kWh of electricity to produce 1.0 kg of aluminum. How much electricity does the plant use for aluminum production in 1 year?
Express your answer to two significant figures and include the appropriate units.


Sagot :

The amount of electricity the plant will use for aluminum production in 1 year is 102×10⁷ KWh of electricity

Data obtained from the question

From the question given above, the following data were obtained:

  • Electricity per Kg of Aluminum = 17 kWh of electricity
  • Electricity for 60000000 Kg of Aluminum = ?

How to determine the amount of electricity needed

The amount of electricity needed to produce the aluminum for 1 year can be obtained as illustrated below:

From the question given above,

1 Kg of Aluminum required 17 KWh of electricity

Therefore,

60000000 Kg of Aluminum will require = 60000000 × 17 = 102×10⁷ KWh of electricity

Thus, the amount of electricity needed to produce the aluminum for 1 year is 102×10⁷ KWh of electricity
