Answer:
46 kg
Explanation:
Ratio of copper to tin in the bronze alloy is 23:2
That means, as a ratio of the entire brass mass, the copper content is in the ratio of 23/(23 + 2) = 23/25
Since the mass of the bronze statue is 50 kg, the mass of copper in it must be 50 x 23/25 = 46 kg
The remaining kg (2/25 of 50 kg) is tin
