The alloy consists of copper, tin and zinc. The mass of tin is m kg, and the mass of copper is 5.2 times greater than the mass of tin. The mass of zinc is 0.08 kg. Find the mass of the alloy at m = 0.6.
Alloy mass = tin mass + copper mass + zinc mass.
Tin mass = m;
copper mass = 5.2 * m;
zinc mass = 0.08 kg.
So, the mass of the alloy = m + 5.2 * m + 0.08 = (1 + 5.2) * m + 0.08 = 6.2 * m + 0.08.
If m = 0.6, then the mass of the alloy: 6.2 * 0.6 + 0.08 = 3.72 + 0.08 = 3.8 kg.
Answer: alloy mass = 3.8 kg.
