Answer:
46.9mg of oxygen
Explanation:
From Henry's law,
Concentration of oxygen (C) = Henry's constant (K) × partial pressure of oxygen in air (p)
K = 1.3×10^-3M/atm O2, p = mole fraction of oxygen in air × pressure of air = 0.21×1.08atm = 0.2268atm
C = K×p = 1.3×10^-3 × 0.2268 = 0.00029484M of O2
Concentration (C) = number of moles of oxygen (n)/volume of water (V)
Volume of water (V) = 4.97L
n = CV = 0.00029484 × 4.97 = 0.001465mole
number of moles (n) = mass of O2/MW of O2
mass of O2 = number of moles of O2 × MW of O2 = 0.001465mole × 32g/mole = 0.0469g = 0.0469×1000mg = 46.9mg (to three significant figures)

Answer:
Atom: The smallest particle of an element that has the properties of the element and can exist either alone or in combination.
Particle: One of the very small parts of matter (as a molecule, atom, or electron)
Kinetic: Of or relating to the motions of material bodies and the forces and energy associated with them
Explanation:
Answer:
Mass stays the same but weight decreases due to a lack of gravity
