1) If 5ml of 0.1M AgNO3 and 1.5ml of 0.25M dextrose (C6H1206) are reacted as in Equation (3), which of the two will be the limiting reagent? (Assume NH3OH and KOH are in excess). 2) If the density of metallic silver is 10.5g/cm³, how many moles of silver atoms are there in a cubic cm of silver metal? 3) Based on your answer to question 2, how many silver atoms are there in a cubic cm of silver metal?
