## How many moles are in 64g of o2?

molar mass of oxygen is 16 grams, it means that 1 mole oxygen weighs 16 grams. therefore 64 gram oxygen = 64/16 = 4 mole oxygen. 1 mole of any element contains 6.022 * 10^23 atoms in it. hence 4 moles of oxygen.

## How many molecules of o2 are there in 64g of o2?

So, in 64 grams of oxygen there are 2.408 x 10^24 oxygen molecules, you should probably just write this answer as 2.4 x 10^24 because this accounts for the significant figures you started out with (you had 2 when we started out with the molar mass of oxygen @ 16) and now, we have two again.

## How many moles of molecules are in oxygen?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## How many moles are in 60 grams of oxygen?

it will be 60g/32g which is equal to 15/8 = 1.875.

## How many grams are in a mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## How many moles of molecules are there in 16 gram of oxygen?

The number of molecules in 16 gm of oxygen are 0.5 (= 16/32 moles). Thus the number of molecules in 16 gm or 0.5 mole of oxygen gas are 0.5 x 6.023 x 10^(23) = 3.012 x 10^(23) molecules.

6×1023.

## How many atoms are in 2 moles of oxygen?

There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .

## How many grams are in 4 moles of oxygen?

4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.
