Answer:
122.04g
Explanation:
Cs is Caesium
Mass of Sn, tin = 109g.
Solution
we must first find the number of moles of the Sn from the given mass:
number of moles = [tex]\frac{mass}{molar mass}[/tex]
molar mass of Sn = 118.7g/mol
number of moles = [tex]\frac{109}{118.7}[/tex] = 0.918moles
Now since the number of moles of the Sn is the sameas that of Cs, we can find the mass of Cs that will equal that.
Mass of Cs = number of moles x molar mass of Cs = 0.918 x 132.9 = 122.04g
