Answer:
7 moles of silver.
Explanation:
Given data:
Moles of NaCl = 12 mol
Moles of Ag = 7 mol
Which have greater mass = ?
Solution:
Mass of NaCl:
Mass = number of moles × molar mass
Mass = 12 mol ×58.5 g/mol
Mass = 702 mol
Mass of Ag:
Mass = number of moles × molar mass
Mass = 7 mol × 107.87 g/mol
Mass = 755.09 mol
Thus 7 mol of silver has greater mas.
