Answer:
The answer to your question is the mass of Iron bar = 469.87 g
mass of rust = 67.13 g
Step-by-step explanation:
Data
mass of Iron bar = 537 g
1/8 turn to rust
final mass of Iron bar = x
final mass of rust = ?
Process
1.- Divide the total mass by eight (numbers of parts)
537g /8 = 67.13 g
2.- The final mass of rust is 1/8 = 67.13 g
3.- Calculate the final mass of the Iron bar
67.13 x 7 = 469.87 g
