1.0006 moles O2
To solve for moles to grams, you use the molar mass (from the periodic table, so for oxygen it is 15.999 grams) to solve for moles this you set up the equation like this:
You would describe the first right molar as supraversion
The best example I
can give that is observable but does not contain matter is:
sunlight or simply light
Light does not contain matter because it is a beam of energy
or to be specific made up of packet of photons.
