Bronze is an alloy made of copper (cu) and tin (sn). calculate the mass of a bronze cylinder of radius 6.44 cm and length 44.37 cm. the composition of the bronze is 79.42 percent cu and 20.58 percent sn and the densities of cu and sn are 8.94 g/cm^3 and 7.31 g/cm^3, respectively. what assumption should you make in this calculation?

49,415.43 gram is the mass of a bronze cylinder.

Explanation:

Assuming that the given composition of bronze is mass percentage of copper and tin in bronze.

Let he mass of bronze be x.

Mass percentage of copper in bronze = 79.42%

Mass of copper = 79.42% of x=0.7942 x

Volume of the copper:

Mass percentage of copper in bronze = 20.58%

Mass of copper = 20.58% of x=0.2058 x

Volume of the copper:

Volume of the bronze cylinder = V

Radius of the cylinder = r = 6.44 cm

Height of the cylinder = h = 44.37 cm

x = 49,415.43 g

49,415.43 gram is the mass of a bronze cylinder.
