What is the mass of sulfur that will react with 0.527 copper metal to yield copper (I)sulfide?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction between copper metal and sulfur to form copper (I) sulfide is:

Cu + S → Cu2S

From the equation, it can be seen that one mole of copper reacts with one mole of sulfur to form one mole of copper (I) sulfide. Therefore, the amount of sulfur needed to react with 0.527 g of copper can be calculated as:

0.527 g Cu x (1 mole Cu/63.55 g Cu) x (1 mole S / 1 mole Cu) x (32.07 g S/mole S) = 0.132 g S

Therefore, the mass of sulfur needed is 0.132 g, which corresponds to answer choice B.
