The mass of Sample A is how many times the mass of Sample B... ok we created an equation 0.21x=8.043...this way, we can solve for x to know

i got 38.3 when i divide it
anonymous
  • anonymous
wait, shouldn't we just multiply the too, and subract 0.21??
LynFran
  • LynFran
no
anonymous
  • anonymous
okay
LynFran
  • LynFran
so when we sub x=38.3 in 0.21x=8.043 0.21* 38.3 =8.043
