How many moles of silver metal are produced from 1.55 moles of copper metal? How many moles of copper(II) nitrate?

1. 3.1 moles of silver, Ag.

2. 1.55 moles of Cu(NO₃)₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Cu + 2AgNO₃ —> Cu(NO₃)₂ + 2Ag

From the balanced equation above,

1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂ and 2 moles of Ag.

1. Determination of the number of mole of silver (Ag) produced.

From the balanced equation above,

1 mole of Cu reacted to produce 2 moles of Ag.

Therefore, 1.55 moles of Cu will react to produce = 1.55 × 2 = 3.1 moles of Ag.

Thus, 3.1 moles of Ag is produced.

2. Determination of the number of mole of copper(II) nitrate, Cu(NO₃)₂ produced.

From the balanced equation above,

1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂.

Therefore, 1.55 moles of Cu will also react to 1.55 moles of Cu(NO₃)₂.

Thus, 1.55 moles of Cu(NO₃)₂ is produced
