Question

Given the reaction Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag, how many steps will it take to convert 64.8 grams of copper to moles of silver? Also, how many moles of silver will be produced?

Answer 1

Answer:

Moles of silver produced =  2 mol

Steps taken = 3 steps

Explanation:

Given data:

Mass of copper = 64.8 g

Moles of silver produced = ?

Steps taken = ?

Solution:

Step 1:

Balance chemical equation:

Cu + 2AgNO₃  →  Cu(NO₃)₂ + 2Ag

Step 2:

Number of moles of Cu:

Number of moles = mass/ molar mass

Number of moles = 64.8 g/ 63.546 g/mol

Number of moles = 1.0 mol

Step 3:

Now we will compare the moles of Ag with Cu from balance chemical equation:

                 Cu          :            Ag

                   1            :            2

Moles of silver will produced:

2 moles
