To determine the limiting reagent between CuSO₄ and NaOH, we first need to look at the balanced chemical equation for the reaction, which is:
[ CuSO₄ + 2 NaOH \rightarrow Cu(OH)₂ + Na₂SO₄ ]
According to the stoichiometry, 1 mole of CuSO₄ reacts with 2 moles of NaOH. First, calculate the moles of CuSO₄ and NaOH. Assuming the molar mass of CuSO₄ is approximately 159.61 g/mol, 638.44 g of CuSO₄ corresponds to about 4.00 moles. For 240.0 g of NaOH (molar mass ≈ 40.00 g/mol), this is about 6.00 moles. Since 4.00 moles of CuSO₄ would require 8.00 moles of NaOH but only 6.00 moles are available, NaOH is the limiting reagent.

How many grams of metallic copper can be obtained when 54.0 g of Al react with 319 g of CuSO4?
To solve this problem, start by writing a balanced chemical equation for the reaction between Al and CuSO4. The molar ratio from the balanced equation indicates that 1 mole of Al reacts with 3 moles of CuSO4 to form 3 moles of Cu. Calculate the moles of Al and CuSO4 in the given masses, determine the limiting reactant, and use stoichiometry to find the mass of metallic Cu produced.
