mass(kg) of pitchblende
Sample Problem 2.1
Calculating the Mass of an Element in a Compound
PLAN:
The mass ratio of uranium/pitchblende is the same no matter the source. We can use this ratio to calculate the answer.
SOLUTION:
mass(g) of pitchblende
mass(g) of uranium
= 86.5 g uranium
= 102kg pitchblende x
mass(kg) pitchblende x
mass (kg) of uranium =
86.5 g uranium x
= 8.65 x 104g uranium
