On average, a tree produces 118 kilograms of oxygen a year. how many molecules of carbon dioxide must a tree take in each year in order to accomplish this? (don't forget to convert kilograms to grams)

a. 1.23 x 1032
b. 2.22 x 1027
c. 3.24 x 1029
d. 3688.9

1. no. of moles of Oxygen = 3687.5 mol

2. amount of CO₂ taken = 3687.5 moles

3. Option B is correct = 2.22 x 10²⁷

Explanation:

Data Given:

Amount of O₂ = 118 Kg

moles of O₂ = ?

no. of molecules of CO₂ = ?

Solution:

First we have to convert Kg to g

Convert unit from Kg to g

1 Kg = 1000 g

118 Kg = 118 x 1000 = 118000 g

Now we will find number of moles of O₂

Mole formula will be used

           no. of moles = mass in grams/ molar mass

molar mass of O₂ = 2(16) = 32 g/mol

Put values in mole formula

          no. of moles = 118000 g/ 32 g/mol

          no. of moles = 3687.5 mol

So we have  3687.5 moles of Oxygen

Part 2:

Now we have to find moles of CO₂ taken by plant to to produce 3687.5 moles of Oxygen

First we will look for the reaction by

            6 CO₂ + 6 H₂O > 6 C₆H₆O₆ + 6 O₂

So,

           6 CO₂ + 6 H₂O > 6 C₆H₆O₆ + 6 O₂

           6 mole                                                 6 mole

So from the above reaction we come to know that 6 moles of CO₂ will be taken to produce 6 moles of O₂

As we Know,

         6 moles of CO₂ ≅ 6 moles of O₂

So,

        3687.5 moles of CO₂ ≅ 3687.5 moles of O₂

So amount of CO₂ taken = 3687.5 moles

Part 3

Now we will find number of molecules of CO₂

Mole formula will be used

           no. of moles = no. of molecules / Avogadro's number

Rearrange the above formula

          no. of molecules =  no. of moles x Avogadro's number . . . . . (1)

Avogadro's number = 6.022 x 10²³

Put values in mole formula (1)

          no. of molecules =  3687.5 moles x 6.022 x 10²³

           no. of molecules =  2.22 x 10²⁷

So ,

Option B is correct = 2.22 x 10²⁷

hi,

the answer is d.indefinite shape but definite volume, let go oogle u out

hope this !

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
