Answer:
6510 kg/m³
Explanation:
Density = Mass/ Volume
D = m/V
Where m = mass of the metal alloy, V = volume of the metal alloy
From Archimedes's principle,
volume of water displace = volume of the metal alloy.
Volume of water displaced = 42.5 - 25.0 mL = 17.5 mL.
Given : m = 114 g = 0.114 kg, V = 17.5 mL = 17.5×10⁻⁶ m³.
Substitute into equation 1
D = 0.114/(17.5×10⁻⁶ )
D = 6.51×10³
D = 6510 kg/m³
Hence the density of the metal = 6510 kg/m³
