What is the volume of 1.60 grams of O2 gas at STP? 1.72 liters 1.45 liters 1.32 liters 1.12 liters

The required volume is 1.12 L.

Explanation:

Given,

Mass of O2 gas= 1.60 grams

We know,

Number of moles = Mass/Molecular mass

                             = 1.60/32                     [Molecular mass of O2 gas is 32 gram]

                             = 0.05

Again,

We know that at STP,

Number of moles = Volume in L / 22.4 L

or, Volume = Number of moles X 22.4

or, Volume = 0.05 X 22.4

or, Volume = 1.12

∴The required volume is 1.12 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.
