When we say STP that means the system is at its standard temperature and pressure. Both systems is having the same condition hence temperature and pressure is constant. We then set the amount of gas in both cases to be equal. Hence from the ideal gas law,
PV=nRT we can say that with everything constant, volume must also be constant.
The answer is (2) 2 L of methane gas.
<u>Question 1</u>
The formula mass of methanol is g/mol.
Therefore, in 5.0 grams of methanol, there are moles.
<u />
<u>Question 2</u>
The formula mass of copper(II) carbonate is g/mol.
This means that in 9.0 grams of copper(II) carbonate, there are moles.
Using Avogradro's number, there are molecules.
<u>Question 3</u>
The formula mass of cyclohexane is g/mol.
So, 3.0 grams of cyclohexane is the same as moles.
<u>Question 4</u>
The formula mass of benzene is g/mol.
This means that 4.00 moles of benzene has a mass of grams.
<u>Question 5</u>
1000 atoms of calcium is the same as moles.
This is equal to grams.
Answer:
the basic unit of a chemical element.
Explanation:
2 Na + SO3 = Na2SO3
Na = 1
SO3 = 1
Na2SO3 = 1
Na = 2
SO3 = 1
Na2SO3 = 1
