You have 3 moles, so there are 3×6.022×1023 oxygen molecules .

## How many molecules of oxygen are in a mole of 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 of oxygen are in acetic acid?

In 1 mole of acetic acid, CH3COOH , 2 moles of oxygen atoms are present.

## How many oxygen molecules are in 2.50 moles of oxygen?

There are 6.022×1023 O2 molecules in a mole of O2. Since you have 2 oxygen atoms in one O2 molecule, there are 2×6.022×1023 O atoms in a mole of O2.

## How many liters of oxygen are there in 2 moles of oxygen?

This means the number of moles of O2 is 222.4=0.089 mol .

## Is o2 2 moles of oxygen?

From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

## What is the mole of oxygen?

Moles of a Substance and the Molecular Weight

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.

## What is the mass of one molecule of oxygen?

O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu. ⇒ 5.31 × 10-23g.

## What is the formula of acetic acid?

CH₃COOH

## How many moles of acetic acid are in 10 mL of vinegar?

The density of acetic acid is 1.05 g/cc at ambient temperature, and the molar mass is 60.05 g/mol. Therefore in 20 ml of vinegar, you will have (1 x 1.05/60.05) = 0.0175 moles of acetic acid. But you cannot quote “moles of vinegar” because vinegar isn’t a compound, its a mixture.

## How many atoms of oxygen is present in 0.5 moles of oxygen?

(ii) 3.011 x 1023 atoms of oxygen.

## How many atoms of oxygen are in 2.5 moles of co2?

3.01 X 1024 Atoms 4.52 X 1024 Atoms 7.53 X 1023 Atoms 5.02 X 1023 Atoms 1.51 X 1024 Atoms.

## How many grams of oxygen does it take to produce 9.60 moles of carbon dioxide?

Now, they’re asking how many grams of oxygen are needed to produce 9.6 grams of carbon dioxide, so that would be 9.6 · 32 / 44, which equals pretty close to 7 grams of oxygen (and 2.6 g of carbon).

## How many liters are in 1 mole of oxygen?

SIDE NOTE More often than not, you will be required to use the old definition of STP, which implies a pressure of 1 atm and a temperature of 273.15 K. Under these conditions, 1 mole of any ideal gas occupies 22.4 L.

## What is the volume of oxygen?

To be able to compare our experimental value to the standard molar volume (22.4 L/mol), we must determine the molar volume at STP (0° C, 1atm). We can use the combined gas law to find the volume the sample of oxygen gas created would have at STP.

## What is the volume of 3 moles of oxygen at STP?

3 moles of oxygen at STP will occupy a volume of 3×22. 4=67. 2 L.
