Given the following equation: Cu + 2 AgNO3 → Cu (NO3) 2 + 2 Ag

How many moles of Cu are needed to react with 3.50 moles of AgNO3?

mols

1.75 moles of copper are needed to react with 3.50 moles of AgNO₃.

Explanation:

Given dа ta:

Moles of copper needed = ?

Moles of AgNO₃ = 3.50 mol

Solution:

Chemical equation:

Cu + 2AgNO₃ → Cu (NO₃) ₂ + 2Ag

Now we will compare the moles of copper and AgNO₃.

AgNO₃ : Cu

2 : 1

3.50 : 1/2*3.50 = 1.75 mol

So 1.75 moles of copper are needed to react with 3.50 moles of AgNO₃.
