How many grams of aluminum will be required to produce 4.5 g of copper metal?

Mass of aluminum required is 1.277 grams

Explanation:

the reaction between copper and aluminium is a redox reaction and this can be written as:

Thus we need two moles of aluminum to reduce or to produce three moles of copper metal.

The moles of copper need to produce

=

These will produced from = of aluminum

The mass of aluminum required = moles X atomic mass = 0.0473X27=1.277g

gravity causes stares to cluster i think so

output?
