Jonnys answer would be the same as his classmates because density does not depend upon the amount or size of a substance but on the composition of the substancw

Answer:

Johnny's result will be identical compared with rest of class

Step-by-step explanation:

  • Density is the ratio of mass to volume
  • If mass increases/decreases then volume also increases/decreases proportionally. Hence density remains constant
  • Johnny ate half of it's brownie. So mass of brownie becomes half of it's original mass. Volume of brownie also becomes half of it's original mass
  • Density of brownie =
    ((mass)_(brownie))/((volume)_(brownie))=(((mass)_(brownie))/(2))/(((volume)_(brownie))/(2))
  • So Johnny's result will be identical compared with rest of class.
