Calculation: The molar mass of oxygen is 16 grams. 1-mole oxygen weighs 16 grams. 64 gram oxygen = 64/16 = 4 mole oxygen.

## What is the number of molecules in 64 gram of oxygen?

so,your answer is 12.04×10^23 molecules.

## How many moles of oxygen do you have if you were given 64.0 g of oxygen?

64.031.9=2.01 moles.

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

For one gram atomic weight of hydrogen with atomic weight of one gram, one mole of hydrogen contains 6.022 × 10^{23} hydrogen atoms. For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 10^{23} oxygen atoms.

## How many moles of oxygen are present in 96g of O2?

Therefore, according to the question, it is given that, weight of ${O_2}$ is 96 grams and is contained in the volume of vessel 2 liters. Hence, the number of moles is 3.

## How many moles are in 64 GS?

Thus there are 64⋅g oxygen gas32⋅g⋅mol−1 = 2⋅mol .

## How many moles of molecules are there in 64 gram of oxygen?

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.

## What is the volume of 64 gram of oxygen at STP?

Therefore, from the above calculations, we can infer that 64 g of oxygen is 44.8 litres at STP.

## How many oxygen molecules are in 32 moles?

One mole of oxygen gas, which has the formula O_{2}, has a mass of 32 g and contains 6.02 X 10^{23} molecules of oxygen but 12.04 X 10^{23} (2 X 6.02 X 10^{23}) atoms, because each molecule of oxygen contains two oxygen atoms.

## How do I calculate moles?

How to find moles?

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How many moles is 50.0 g of oxygen?

There are 3 moles of O in 50 g.

## How many moles are in 12.0 grams of O2?

Therefore, 12 g of oxygen gas has 0.375 moles.

## What is the 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 are in 96g?

Approx. 6⋅mol .

## How many moles are present in 96g of ozone?

Solution : Gram molecular mass of `O_(3)=48 “g mol”^(-1)` <br> No. of moles of ozone `(O_(3))` in 96 g `= ((96 g))/((48″g mol”^(-1)))=2mol` <br> 1 mole of ozone has oxygen atoms `= 3 “mol” = 3 xx N_(A)` <br> 2 mole of ozone has oxygen atoms `= 6 xx N_(A) = 6 xx 6.022 xx 10^(23)` <br> `=3.612 xx 10^(24)` atoms.

## How many moles are in 80g of oxygen?

Gram atomic mass of Oxygen is 16 g. Therefore, 80 g of Oxygen will contain = 80/ 16 = 5 moles.
