Hi,
how many moles does 0.225g of oxygen atoms represent?
If 1 mole of oxygen atoms represents 16.0g?
Thanks
mols = grams/molar mass.
thot so.
Thanks for confirming ;)
This is right for oxygen atoms, however, oxygen in the atmosphere is O2, and we normally think of a mole of O2 molecules. Make certain which you need.
thanks
You're welcome! If you're specifically referring to oxygen atoms (O), then we can use the formula:
moles = grams / molar mass
Given that 1 mole of oxygen atoms represents 16.0g, we can plug in the values:
moles = 0.225g / 16.0g/mol
Calculating this will give you the number of moles represented by 0.225g of oxygen atoms.
However, it's important to note that in the atmosphere, oxygen is typically found as O2 molecules. If you need to calculate the number of moles of O2 molecules, you will need to consider the molar mass of O2, which is 32.0g/mol.
