# Best answer: How many grams are in 3 moles of oxygen gas O2?

Contents

## How many molecules of oxygen gas are in 3.0 moles of oxygen gas?

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

## How many O2 molecules are there in 3 moles of O2?

According to Avagadro, there are 6.022 × 10^23 molecules in 1 mole of any compound, irrespective of elements or the mass of compound. Thus in 3 moles of O2, there are 3 ×6.022× 10^23 molecules of O2, that is, 18.066×10^23 molecules of O2.

## 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.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.

## How many atoms are in 3 moles of oxygen?

1 mole of a substance there are 6.022*10^23 atoms/molecules. From this we can deduce that there are 3*6.022*10^23 O2 molecules in 3 moles.

## What is K mole?

39.10 grams is the molar mass of one mole of K.

## How many molecules is 3 moles?

Do 3 moles x (6.022 x 10^23 molecules / 1 mol) to get about 1.8 x 10^24 molecules.

## How do I calculate moles?

How to find moles?

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

## How many moles are in 64 grams 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.
