How many moles are present in 2.6 g of CO2?

0.059 moles are present in 2.6 g of CO₂

Explanation:

Molar mass is the mass of one mole of a substance, which can be an element or a compound. That is, it is the amount of mass that a substance contains in one mole.

In this case, the mass of each element being:

then the molar mass of the compound is:

CO₂=  12 g/mole + 2*16 g/mole= 44 g/mole

Then you can apply the following rule of three: if by definition of molar mass 44 grams of CO₂ are present in 1 mole, 2.6 grams will be present in how many moles?

amount of moles= 0.059 moles

0.059 moles are present in 2.6 g of CO₂

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.
