Question #9 please
Transcribed Image Text:Once you know the percentage composition of (Sample Problem. A 40.0 g sample of CaCl,-2H,0 is heated to dryness. What is the
a compound, you can figure out the mass of any mass of the remaining calcium chloride.
component of the compound in a sample of any
mass simply by multiplying the sample mass by Formula Mass of CUSO, Formula Mass of H,O
H = 1 x 2 = 2
O = 16 x 1 = 16
18
the percentage. See the Sample Problem to the Ca = 40 × 1 = 40
CI = 35 x 2 = 70
0 = 16 x 4 = 110
right.
Mass of Water: 2 x 18 = 36 TOTAL: 110 + 36 = 146
How many milligrams of iron are
delivered from a 250. mg tablet of
FeSO,-7H,O?
8.
Percentage
%CaCl, = 110 x 100
+ 146 = 75 %
Mass
0.75 x 40.0 g = 30. g

What is the yield of uranium from 2.50 kg U,O,?
Expert Solution
Step 1
Q9)
U3O8 molar mass
Atomic mass of U =238
Atomic mass of oxygen =16
Molar mass of U3O8 = 3(238) + 8(16)
= 842 g/mol
One mole U3O8(842 g) yield 714 g of uranium
2500 grams of U3O8 yield => (2500 g * 714) g /842 g
= 2119.95 g
= 2.12 kg
