Short-Question

# How many molecules are in 48 grams of O2?

## How many molecules are in 48 grams of O2?

033×1023. molecules are present in 48.0 grams of oxygen gas.

## What is the number of moles of oxygen 02 in 24 g of 02?

of moles × atomic mass = 2 × 12 = 24 g. Question 3. Calculate the number of oxygen atoms in 1 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 molecules of oxygen are there in 1 g sample of O2?

The molar mass from the periodic table is 32.00 g O2 = 1 mol O2, and by definition, 1 mol O2 = 6.02 × 1023 molecules O2.

How many moles of co2 are there in 48 grams of oxygen?

Hence 48g O₂, produces = 1.5 mole of CO₂. Therefore, the answers is 1.5 moles of CO₂.

### How many moles of atoms are present in 48 g oxygen?

The number of moles can be calculated by dividing the given mass to molar mass. The molar mass of ozone is 48g as each oxygen atom has mass has 16g and there are three oxygen atoms. So one mole of ozone is equal to 48g.

### What is the molar mass of 02?

15.999 u
Oxygen/Atomic mass

How many moles are in 24 g?

There are 2 moles in 24 g of Mg.

How many molecules are in 2 gram of O2?

We know that 2g of O2 has 0.0625 moles of O2. That means that the number of O2 molecules present in 2g of O2 is equal to 0.0625*NA. That’s 3.76375*10^22. That is a lot of molecules.

## How many oxygen molecules are there?

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 grams of O2 equal to a mole?

More information from the unit converter. The answer is 31.9988. We assume you are converting between grams O2 and mole. You can view more details on each measurement unit: molecular weight of O2 or mol The SI base unit for amount of substance is the mole. 1 grams O2 is equal to 0.031251171918947 mole.

How many molecules of oxygen are in 50.0 g of oxygen?

So in 50.0 grams of O2 there would be about 940983018325458136453411 molecules of O2 and about 1881966036650916272906822 atoms of (O). 1.5625 mol contains 1.5625 mol * 6.022*10^23 molecules/mol = 9.41*10^23 molecules (answer given to 3 significant digits.)

How is the oxygen stored in the atmosphere?

The atmospheric air consists of about 21% oxygen, 78% nitrogen, and then other gases. The oxygen concentrator works by absorbing air from the surroundings and filtering out nitrogen and other gases. The absorbed oxygen is stored in a cylinder to be inhaled by the user.
