# I say I love my wife more than every grain of sand on the earth. She says more than every molecule of oxygen on the earth. Which one is more?

no brainer. every molecule of quartz has 2 oxygens, and there are huge numbers of SiO2 molecules in even the smallest of sand grains, never mind all the oxygen everywhere else on earth.

There are more molecules and atoms of oxygen. Oxygen IS IN sand, which is usually silicon dioxide, SiO2. Sand is also again size.

There is more oxygen in one of her boogers than grains of sand on Earth.

There are more molecules of oxygen than there are grains of sand.

Sand has oxygen, so does air and water and all plants, animals, most rocks.

oxygen is more i'm pretty sure

internet:

the Earth has roughly (and we're speaking very roughly here) 7.5 x 10^18 grains of sand

Oxygen itself makes up approximately 46.6 percent of the crust and 30 percent of the mass of the entire Earth.

Earth Mass 5.97e24 kg

30% of that is about 2e24 kg or 2e27 g

O atoms are 16 g/mol

2e27 g / 16 g/mol = 1.2e26 mol

6.022e23 atoms/mole x 1.2e26 mole = 8e49

so 8e49 O atoms is much much more than 7e18, about 1e31 factor,

which is 10000000000000000000000000000000

now I did O atoms, not molecules, because she said "on the earth" which includes oxygen in rocks, which are not in oxygen molecules.

But even if you divide that number by 1000, it is still much much larger.

look at it another way, how much oxygen would it take for oxygen molecules to equal the number of grains of sand...

6.022e23 atoms/mole x M = 7.5e18

M = 0.0000125 moles

or multiplying by 32, that is

0.0003985 grams, a miniscule amount.
