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
