The container that has lowest temperature will store more amount of gas as compared to high temperature container.
Which container has gas stored at the highest temperature?At lowest temperature, the container stored the large amount of gas because at lower temperature the gases contract so more space is available for the storage of more gases.
So we can conclude that the container that has lowest temperature will store more amount of gas as compared to high temperature container.

How many grams of C8H18
is in 405,576.398 mL
[tex]Molarity X \frac{0.762 mol}{05.576398 L} = Mass[/tex] is the of [tex]C_8H_1_8[/tex] is in 405,576.398 mL.
What is molarity?Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Molar mass of [tex]C_8H_1_8[/tex] = 0.762 mol
Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L
Solution:
Step 1: Calculating moles of [tex]C_8H_1_8[/tex]
• Molarity =[tex]\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}[/tex]
• Putting the value in the given formula
• Moles of solute C8H18 = [tex]\frac{\;Mass}{\;Molar \;molar \;mass}[/tex]
• Moles of solute C8H18 = [tex]\frac{\;Mass}{0.762 mol}[/tex]
Now,
Molarity =[tex]\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}[/tex]
Molarity =[tex]\frac{\frac{\;Mass}{0.762 mol}}{\;Volume \;of \;solution \;in \;litre}[/tex]
Molarity =[tex]\frac{\frac{\;Mass}{0.762 mol}}{405.576398 L}[/tex]
[tex]Molarity X \frac{0.762 mol}{05.576398 L} = Mass[/tex]
Hence, [tex]Molarity X \frac{0.762 mol}{05.576398 L} = Mass[/tex] is the of [tex]C_8H_1_8[/tex] is in 405,576.398 mL.

Given a balance chemical equation, 2 H2(g) O2(g) 2 H2O(g) If a reaction mixture contains 3 moles of O2(g) with 4 moles of H2(g), which reactant is the limiting reactant and what is the mass remaining of the reactant in excess
We have the equation [tex]2\text{H}_{2}+\text{O}_{2} \longrightarrow 2\text{H}_{2}\text{O}[/tex].
This means that for every mole of oxygen consumed, 2 moles of hydrogen are consumed.
Considering the oxygen, the reaction can occur 3 times.Considering the hydrogen, the reaction can occur 4/2=2 times.Therefore, hydrogen is the limiting reactant.
If all 4 moles of the hydrogen are consumed, then 2 moles of the oxygen will be consumed. This means 1 mole of oxygen, which has a mass of 15.9994 grams, will remain.

b) 44.8
c) 11.2
d) 5.6
an explanation would be great for future reference <3 thank you in advance!
Answer:
5.60 Liters at STP
Explanation:
First you need the balanced reaction equation
2 H2 + O2 ====> 2 H2O
4 g of oxygen ( O2 ) is 4/(15.999*2) moles of O2 (using periodic table)
Twice the number of moles of H2O re produced (from equation)
at STP the volume of a mole of gas is 22.4 liter/ mole
put all of this together
2 * 4 / (15.999*2) moles * 22.4 L/mole = 5.60 L
