Examine the statement and balanced equation.

Answer 1

Answer:

The answer to your question is:   1.28 x 10 ¹⁵ g of Fe₂(SO₄)₃

Explanation:

Single replacement reaction:

                                  2Fe   +    3H₂SO₄    →    Fe₂(SO₄)₃   +   3H₂

M Fe = 55.8 g/mol

M H₂SO₄ = 98.1 g/mol

M Fe₂(SO₄)₃ = 399.9 g/mol

M H₂ = 2.0 g/mol

Fe₂(SO₄)₃ = 3.21 x 10¹² mol

Fe₂(SO₄)₃ =  ? g

                          1 mol of Fe₂(SO₄)₃ -----------------  399.9 g/mol of Fe₂(SO₄)₃

                          3.21 x 10¹² mol Fe₂(SO₄)₃ --------    x

   

                         x = (3.21 x 10¹² x 399.9 ) / 1

                         x = 1.28 x 10 ¹⁵ g of Fe₂(SO₄)₃
