Question 1

On the planet Kracalac, in another solar system, argon has three naturally occurring isotopes as follows:

     Isotope                         Mass (amu)                              Natural Abundance (%)

     Argon-36                     35.968                                     10.65

     Argon-38                     37.963                                     15.15

     Argon-40                     39.962                                     74.20

 

What is the average atomic mass of argon on Kracalac?


◦ 35.97 amu
◦ 39.96 amu
◦ 37.96 amu
◦ 39.23 amu
◦ 40.00 amu

Question 2

One commercial system removes SO2 emissions from smoke at 95.0°C by the following set of balanced reactions:
              SO2 + Cl2→ SO2Cl2
              SO2Cl2 + 2H2O → H2SO4 + 2HCl
              H2SO4 + Ca(OH)2→ CaSO4 + 2H2O
Assuming the process is 95.0% efficient, how many grams of CaSO4 may be produced from 100. grams of SO2?
(molar masses: SO2, 64.1 g/mol; CaSO4, 136 g/mol)

◦ 44.8 g
◦ 47.1 g
◦ 87.2 g
◦ 202 g
◦ 212 g
