1-mole oxygen weighs 16 grams. 64 gram oxygen = 64/16 = 4 mole oxygen. “1 mole of any element contains 6.022 × 1023 atoms.”

## How many molecules are in 64 grams of O2?

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

## How many grams are in 1 mole of oxygen gas?

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 is 32 grams of oxygen?

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 many moles are in 40 grams of oxygen?

∴ There are 1.25 moles of O2 in 40g of oxygen gas.

## How many moles and molecules of o2 are there in 64 gram of o2 What is the mass of 1 molecule of o2?

How many molecules are present in 10g of H2O?

## 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 50 grams of o2?

To calculate the weight of an element in grams to moles, we should know the molar mass of an element. For example, 50 grams of oxygen is equal to 3 moles.

## How many grams are in moles?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## How many moles are in 12.0 grams of o2?

Therefore, 12 g of oxygen gas has 0.375 moles.

## How many moles are in 16g of oxygen?

Here, it is given that: 16 g of oxygen contains 1 mole of oxygen atoms. In simple terms we can say that: mass of 1 mole oxygen atom (W) = 16 g / mol.

## How many moles are there in 500 g of oxygen?

The answer is 0.062502343837894. We assume you are converting between moles Oxygen and gram. You can view more details on each measurement unit: molecular weight of Oxygen or grams The molecular formula for Oxygen is O.

## How many moles of o2 are in 48 g o2?

48 g of individual oxygen atoms = 3 moles of oxygen atoms.

## What is number of mole?

A mole is defined as the mass of the substance which consists of the equal quantity of basic units. Example atoms in 12 grams are the same as 12C. A mole fraction indicates the number of chemical elements. … One mole of any substance is equal to the value of 6.023 x 10^{23} (Avagadro number).
