The correct answer is C. Plz mark brainiest
Explanation:
Percent yield is simply the ratio of the actual amount
produced over the theoretical amount that can be produced. In this case that
would be:
percent yield = actual amount / theoretical amount
percent yield = (14.5 g / 22.0 g) * 100%

Answer:
Geology
Explanation:
Geology is not a branch of biology.
Biology is the study of all forms of lives. Bio - life and logy - study
It consists of studies of plants, animals and micro-organisms. Some of its sub-branches are zoology, botany, genetics, micro-biology e.t.c.
- Geology is the study of the earth.
- It deals with the materials that makes up the earth and how they have evolved through time.
- some of its sub-disciplines are hydro-geology, stratigraphy, geochemistry e.t.c
To answer this item, it is assumed that O2 is an ideal gas such that it follows the ideal gas law.
PV = nRT
Solving for n,
n = PV / RT
where n is number of moles, P is pressure, V is volume, R is the universal gas constant, T is the temperature.
Substituting the known values,
n = (724 mmHg/760 mmHg/1 atm)(1 L) / (0.0821 L. atm/mol.K)(298 K)
Simplifying,
n = 0.0389
Hence, the value of n is 0.0389.
