• An experiment was set up to investigate rusting.
  Some clean, shiny, iron nails were sealed in a
  glass bottle containing some tap water. The
  sealed bottle was then placed on a top-pan
  balance. The reading on the balance was 549.8g.

• The sealed bottle was left for one week. After
  one week the nails were rusty.
• (i) What would you expect the reading on the
  balance to be after one week?
