D moles of solid copper used in reaction convert from grams

Question

D. moles of solid copper used in reaction [Convert from grams to moles by dividing the grams of copper by the atomic mass (Cu = 63.55 g/mol)] (mol):

E. moles of solid silver produced in reaction [Convert from grams to moles by dividing the grams of silver by the atomic mass (Ag = 107.84 g/mol)] (mol):

2. Write the equation for the reaction between copper and silver ion. Include your experimentally determined mole ratios as fractional coefficients.

3. Convert the fractional coefficients to a whole number ratio and rewrite the equation using the whole number ratio.

4. If the silver in the beaker contained water during your last weighing, how would this affect your results?

5. Assume that magnesium would act atom-for-atom exactly the same as copper in this experiment. How many grams of magnesium would, have been used in the reaction if one gram of silver were produced? The atomic mass of magnesium is 24.31 g/mol.
