Answer:
25.5 g
Explanation:
First, you will need a balanced chemical equation
CuO + H₂ ==> H₂O + Cu
From the equation above, we can see that for every 1 mole of CuO (copper(II) oxide), 1 mole of Cu (copper) is produced.
Convert grams of CuO to moles. You should get 0.402 mol. Now with the relationship established above, you can see that you should ideally get 0.402 mol. Convert this to grams. Your answer should be 25.5 g.
According to the statement, The mass of copper can be obtained if 32.0g of copper(II) oxide is used = 25.5 g
Willingly, you will require a balanced chemical equation
CuO + H₂ ==> H₂O + Cu
From the equation overhead, we can see that for every 1 mole of CuO (copper(II) oxide), 1 mole of Cu (copper) is produced.
Convert grams of CuO to moles. You should reach 0.402 mol. When the relationship is specified above, you can notice that you should ideally get 0.402 mol. Reverse this to grams. Therefore The correct option is B. which is 25.5 g.
