Answer:
0.32mole
Explanation:
Given parameters:
Mass of tin cup = 38.1g
Unknown:
Number of moles in the cup = ?
Solution:
To find the number of moles, use the expression below;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass = 118.7g/mol
So;
Insert the parameters and solve;
Number of moles = [tex]\frac{38.1}{118.7}[/tex] = 0.32mole
