Question

Using the chemical equation below, how many grams of Fe produce when 7 moles of Fe2O3 are reacted ? 2Al+Fe2O3 —> Al2O3+2Fe

Answer 1

784 g.

Step-by-step explanation:

Since 1 mole of
`Fe_2O_3` gives us 2 moles of $Fe$, 7 moles $Fe_2O_3$ will give us 14 moles of $Fe$

Molar mass of $Fe$= 56 g/mol

Thus, mass of 14 moles is $14 \times 56= \boxed{784}$
