Liters of Oxygen : 61.6 L

Given

5.5 moles Na₂O

Required

Liters of Oxygen

Solution

Reaction

4Na+O₂⇒2Na₂O

mol O₂ from equation :

= 1/2 x mol Sodium oxide

= 1/2 x 5.5

= 2.75

Assume at STP(1 mol gas=22.4 L), liters O₂ :

= 2.75 x 22.4

= 61.6 L

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
