A geologist analyzed a sample of bauxite ore to determine its purity.

From an initial sample of 23.8 g23.8\text{ g}23.8 g of raw bauxite ore, the geologist successfully extracted 6.4 g6.4\text{ g}6.4 g of pure alumina (Al2O3\text{Al}_2\text{O}_3Al2​O3​).

Assuming the ore is of uniform composition, calculate the mass of pure alumina that could be extracted from a 55.5 g55.5\text{ g}55.5 g sample of the same bauxite ore.

Give your answer to 3 significant figures.
