Answer:
The concentration of helium in the water is 2.405×10^-4 M
Explanation:
Concentration = Henry's law constant × partial pressure of helium
Henry's law constant = 3.7×10^-4 M/atm
Partial pressure of helium = 0.65 atm
Concentration = 3.7×10^-4 × 0.65 = 2.405×10^-4 M

Answer:
A. The volume of the water in the graduated cylinder is equal to the volume of the object.
Explanation:
The round object have a higher density than the water (because the objects sinks at the bottom at the beaker as seen in the picture) and will displace a volume of water equal to its own volume. The water will fall from the beaker in the graduated cylinder where the volume may be read. In this scenario we assume that the object will not react with the water.
Answer:
71.1 mol CO2 ( 1 mol CH4 / 1 mol CO2 ) = 71.1 mol CH4 produced
