SpongeBob loves to garden and wants to grow lots of pink flowers for his pal Sandy. He brought a special Flower Power fertilizer

to see if it will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilized water. He places the other plant on a shelf in a closet and waters it with plain water every other day.
What did SpongeBob do wrong in this experiment? Explain.

How could SpongeBob improve his experiment?

Answer: He had more than one independent variable.

Explanation: It would only be fair, if both plants were in a sunny window, because then, it would be easier to see if the fertilizer actually affected the plants. This is because there is always a chance that the lack of sunlight decreased the number of flowers on the plant, instead of the fertilizer. It is always better to just have one independent variable.

The Henry's law constant (kH) for O2 in water at 20°C is 1.28e-3 mol/l atm. How many grams of O2 will dissolve in 3.5 L of H2O t
Sophie [7]

Answer : The mass of O_2 dissolved will be, 0.2365 grams

Explanation :

First we have to calculate the concentration of O_2.

As we know that,

C_{O_2}=k_H\times p_{O_2}

where,

C_{O_2} = concentration of O_2 = ?

p_{O_2} = partial pressure of O_2 = 1.65 atm

k_H = Henry's law constant = 1.28\times 10^{-3}mole/L.atm

Now put all the given values in the above formula, we get:

C_{O_2}=(1.28\times 10^{-3}mole/L.atm)\times (1.65atm)

C_{O_2}=2.112\times 10^{-3}mole/L

The concentration of O_2 = 2.112\times 10^{-3}mole/L

Now we have to calculate the moles of O_2

\text{Moles of }O_2=\text{Concentration of }O_2\times \text{volume of solution}

\text{Moles of }O_2=(2.112\times 10^{-3}mole/L)\times (3.5L)=7.392\times 10^{-3}mole

Now we have to calculate the mass of O_2

\text{Mass of }O_2=\text{Moles of }O_2\times \text{Molar mass of }O_2

\text{Mass of }O_2=(7.392\times 10^{-3}mole)\times (32g/mole)=0.2365g

Therefore, the mass of O_2 dissolved will be, 0.2365 grams
