Neco Model Questions Vol1 2024 Chemistry Question 42
Practice objective / multiple choice question 42 from the 2024 Neco Model Questions Vol1 Chemistry examination.
An alloy contains metals A (density 8.0 g·cm^{-3}) and B (density 10.0 g·cm^{-3}). The total mass of the alloy is 500 g and its total volume is 55 cm^{3}. (a) Determine the mass percent of each metal in the alloy. (b) The alloy is immersed in a corrosive medium where metal A loses mass at a rate of 0.02 g·cm^{-2}·day^{-1} and metal B at 0.05 g·cm^{-2}·day^{-1}. If the exposed surface area is 100 cm^{2}, calculate the total mass loss after 30 days and give the final mass of the alloy.
