Answer to Question #204797 in General Chemistry for Ayame

Question

127 grams of copper completely reacts with silver nitrate in the reaction Cu + 2 AgNO₃ -> CuNO₃)₂ + 2 Ag

how many moles of AgNO₃ are consumed?

Answer 1

Molar Mass of copper = 63.546

127/63.546 = 1.9985 M

Molar Mass of AgNO₃ = 169.87

Mole ratio = 1Cu : 2 AgNO₃

= 2 × 1.9985 = 3.997 moles of AgNO₃
