First, we need to find the volume occupied by 22.1 g of cobalt using its density: 
density = mass/volume 
8.90 g/cm³ = 22.1 g/volume 
volume = 2.48 cm³ 
Now, we need to find the mass of silver that occupies the same volume, using its density: 
density = mass/volume 
10.50 g/cm³ = mass/2.48 cm³ 
mass = 26.1 g 
Therefore, the mass of silver that occupies the same volume as 22.1 g of cobalt is 26.1 g, so the best choice is B.
