Approx.
Explanation:
The molar volume of
For the molar quantity of this mass of dioxygen gas we have....
And so to find the volume occupied by the molar quantity, we take the product....
Note that you must simply know that ALL elemental gases SAVE the NOBLE GASES, are bimolecular, i.e. dinitrogen, dioxygen, difluorine, dichlorine....
Use the molar volume (
Explanation:
We can use dimensional analysis to convert from:
First, let's calculate the molar mass of
Now, we are ready to begin:
Your final answer is therefore
I hope that helps!
Explanation:
Molar mass of
Number of moles = mass in grams/ molar mass.
1 mole of of
So:
48
Explanation:
At GCSE level, I was taught that one mole of gas occupies a volume of 24
I will show you the calculation for both.
First we need to calculate how many moles of
mass=64.0g
Mr(
moles=
If 1 mole of
2 moles of
If 1 mole of
2 moles of
