Density is a measure of (4 points)
2 answers:
Density is a measure of mass divided by volume.
density is mass of the substance for a unit volume
Density is also referred to as ρ.
A large mass spread over a small volume is said to have a high density. Some substances could have a large mass spread over a very large volume, those are said to have a small density.

Answer:
The mass of oxygen gas dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air is 0.04936 grams.
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= partial pressure of oxygen
We have :
Pressure of the air = P
Mole fraction of oxygen in air =
= Henry's constant =
Putting values in above equation, we get:
Moles of oxygen gas = n
Volume of water = V = 5 L
Mass of 0.001542 moles of oxygen gas:
0.001542 mol × 32 g/mol = 0.04936 g
The mass of oxygen gas dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air is 0.04936 grams.
