Question

How many grams of Ag will be produced from 5.00g of Cu and 1.00g of AgNO3​

Answer 1

0.635 g of Ag

Step-by-step explanation:

Below are attachments containing the solution

Answer 2

0.635 grams

Step-by-step explanation:

Equation for the reaction

`Cu + 2 AgNO_3 -----> Ag^(2+) + CuNO_3`

mass of Cu = 5.00 g

molar mass = 63.5 g/mol

number of moles =
`(mass)/(molar mss)`

number of moles of Cu =
`(5.00g)/(63.5g/mol)`

number of moles of Cu = 0.0787 moles

To determine the moles of Ag formed; we have:

0.00588 moles of AgNO₃ ×
`(2 moles of Ag)/(2 moles of AgNO_3)`

= 0.00588 moles of Ag are produced

Molar mass of Ag = 108 g/mol

Then mass of Ag that will be produced = number of moles of Ag × molar mass of Ag

= 0.00588 moles × 108 g/mol

= 0.635 grams of Ag are produced.
