Brass

Brass is an alloy of copper and zinc in a ratio of 3: 2. How many grams does a component that required 270 g of copper weigh?

Result

m =  450 g

Solution:

m1=270 g  m1=33+2 m  m=53 m1=53 270=450 gm_{1}=270 \ \text{g} \ \\ \ \\ m_{1}=\dfrac{ 3 }{ 3+2 } \cdot \ m \ \\ \ \\ m=\dfrac{ 5 }{ 3 } \cdot \ m_{1}=\dfrac{ 5 }{ 3 } \cdot \ 270=450 \ \text{g}
