B.) The piece of copper wire from the previous problem weighed 4.37g before the reaction and 4.15 g after the reaction. What actual mass of copper reacted?
BALANCED EQUATION: Cu + 2AgNO3 --> Cu(NO3)2 + 2Ag

C.) Determine the experimental mole-ratio of copper to silver nitrate by dividing the moles of copper that actually reacted to the moles of silver nitrate that actually reacted (express your mole ratio as a decimal to the 0.001 place). Does this ratio agree with the mole ratio from the balanced equation?
