We have that for the Question "" it can be said that the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is
Amount of CO_2(g)=221.35g
From the question we are told
What is the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules?
Generally the equation for the is mathematically given as
[tex]No moles in 3*02*10^{24}=\frac{3.03*10^{24}}{6.023*10^-{23}}[/tex]
No moles in 3*02*10^{24}=5.03moles
Amount of CO_2(g)=5.03moles *44g/mol
Amount of CO_2(g)=221.35g
Hence
the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is
Amount of CO_2(g)=221.35g

More bushes of potatoes will be produced if the soil is fertilized more WHAT IS THE INDEPENDENT VAIRABLE AND THE DEPENDENT VARIABLE
Answer:
The dependent variable is the bushes of potatoes while the soil is an independent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Hence, the dependent variable is the bushes of potatoes while the soil is an independent variable.

If 95 grams of Iron are needed to react with sulfur, how many grams of sulfur are involved in this reaction?
2 Fe + 3 S=Fe2S3
Answer:
82 g S
Explanation:
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 81.6 grams of sulfur are involved in this reaction.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
2 Fe + 3 S[tex]\rightarrow[/tex]Fe[tex]_2[/tex]S[tex]_3[/tex]
mass of iron = 95 grams
Molar mass of iron=55.8450 g/mol
number of moles of iron =Given mass÷ Molar mass of iron
number of moles of iron=95÷ 55.8
number of moles of iron=1.70 moles
The mole ratio between iron and sulfur is 2:3
moles of sulfur = (3/2) moles of iron
moles of sulfur = (3/2)×1.70
moles of sulfur=2.55 moles
Mass of sulfur= number of moles of sulfur× Molar mass of sulfur
=2.55× 32
=81.6g
Therefore, 81.6 grams of sulfur are involved in this reaction.

If the football indoors had a volume of 5.33 L at 21degrees celsuis, what is the volume of the football outside where the temp is 10C (temp must be in K) MUST SHOW WORK
Answer:
5.13 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 5.33 L
Initial temperature (T₁) = 21 °C
Final temperature (T₂) = 10 °C
Final volume (V₂) =?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T₁) = 21 °C
Initial temperature (T₁) = 21 °C + 273
Initial temperature (T₁) = 294 K
Final temperature (T₂) = 10 °C
Final temperature (T₂) = 10 °C + 273
Final temperature (T₂) = 283 K
Finally, we shall determine the final volume. This can be obtained as follow:
Initial volume (V₁) = 5.33 L
Initial temperature (T₁) = 294 K
Final temperature (T₂) = 283 K
Final volume (V₂) =?
V₁/T₁ = V₂/T₂
5.33 / 294 = V₂ / 283
Cross multiply
294 × V₂ = 5.33 × 283
294 × V₂ = 1508.39
Divide both side by 294
V₂ = 1508.39 / 294
V₂ = 5.13 L
Thus, the new volume of the football is 5.13 L

A sample of methane gas, CH4, occupies 3.25 L at temperature of 19.0 o C. If the pressure is held constant, what will be the temperature be if the volume expands to 10.00 L?
Answer:
625.46 °C
Explanation:
We'll begin by converting 19 °C to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
T(°C) = 19 °C
T(K) = 19 °C + 273
T(K) = 292 K
Next, we shall determine the Final temperature. This can be obtained as follow:
Initial volume (V₁) = 3.25 L
Initial temperature (T₁) = 292 K
Final volume (V₂) = 10 L
Final temperature (T₂) =?
V₁/T₁ = V₂/T₂
3.25 / 292 = 10 / T₂
Cross multiply
3.25 × T₂ = 292 × 10
3.25 × T₂ = 2920
Divide both side by 3.25
T₂ = 2920 / 3.25
T₂ = 898.46 K
Finally, we shall convert 898.46 K to celsius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 898.46 K
T(°C) = 898.46 – 273
T(°C) = 625.46 °C
Therefore the final temperature of the gas is 625.46 °C

How is a calorimeter used in this experiment different from the ones used to find the energy content of a snack
Answer:
Kindly check the explanation section.
Explanation:
PS: Note that enough information are not being provided and we do not know the experiment this question is all about. However, some information are provided below which is going to aid in solving when you get access to the main question.
The determination of the heat transferred from one substance to another is one of the important aspect in science. The method in which this heat is being measured is known as calorimetry and the instrument used in this technique is known as the calorimeter.
When the energy content of a snack is needed to be calculated, there is the need use a type of instrument known as bomb calorimeter.
Most of the calorimeters used by students are not so expensive like the used in the industries. Most of these calorimeters operates at a constant pressure while the Bomb Calorimeter operates at constant volume.
