First, we can use the density of cobalt to calculate its volume:

V = m/d = 95.7 g / 8.90 g/cm³ = 10.73 cm³

Since aluminum occupies the same volume, we can use its density to calculate its mass:

m = V x d = 10.73 cm³ x 2.71 g/cm³ = 29.1 g

Therefore, the mass of aluminum that occupies the same volume as 95.7 g of cobalt is 29.1 g. The correct answer is (B).
