Question 5
Only
12.0%
of particles contain analyte
(p
)
=

Question 6
_(_())_(_())
A representative sample requires
n
particles (from Q5). A current grab of those n particles weighs 50.0 g . If particles are spherical and mass
=r^(3)
, to reduce the same n particles to 0.800 g . by what factor must particle radius be reduced?
