3 moles of Oxygen atoms weigh 48.00 grams.

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

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

## How many grams is a mole of O2?

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 O2 atoms are there in 3 moles of O2?

3*6.023*10^23 = 18.069*10^23 molecules of O2. Hey! 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 3.5 moles of O2?

The atomic mass of oxygen is approximately 16 grams, however o2 would make it 32 grams. Then one would multiply 32 by 3.5 moles which would give you 112 grams per 3.5 moles.

## What is 3 moles O2?

3 moles of Oxygen atoms weigh 48.00 grams.

## How much is 3 moles?

One mole of any substance. =Gram Atomic weight or gram molecular weight of that substance. Three mole of water weighs=18*3=54 Gram.

## How many grams are in a mole?

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 grams are in 1 mole of CO2?

Molar Masses of Compounds

The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g.

## How many moles of oxygen are in O2?

A mole of O2 molecules has 6.023E23 molecules, and each molecule is made up is two atoms of oxygen. That means that there are two moles of oxygen atoms in a mole of O2, or 1.2046E24 of them.

## What is the mass of 3 moles of oxygen gas O2 o 16?

Next, we calculate the molar weight of oxygen (diatomic, remember). This means we have to double 15.999g/mole. Thus, diatomic oxygen is 32g/mole. Three moles is 96g.

## How many oxygen atoms are in a mole of O2?

Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.

## How many grams are in 3.5 moles?

The mass of 3.5 moles of Ca is 140 g to two significant figures.

## How many grams are there in 3.5 moles of water?

The mass of water is 3.5 moles*18g/mole=63g.

## How many grams are in 3.5 moles of As atoms?

Please note that here we gots 3.5⋅mol of arsenic ATOMS, a mass of 262.1⋅g .
