3 moles of Oxygen atoms weigh 48.00 grams.

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

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

## How many grams is 3 moles of water?

similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=54 gram.

## How many grams of oxygen are in one mole of water?

Moles of a Substance and the Molecular Weight

One mole of Water is composed of 1 mole of Oxygen and two moles of Hydrogen. 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 of oxygen are in 2 moles of water?

Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

## How many atoms are in 2 moles 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 molecules are in 23.0 moles of oxygen?

The number of molecules of oxygen in 23 moles of oxygen is 1.385 x 1025 molecules of oxygen.

## How many moles are in 50g of water?

1 Answer. There are 3 moles of O in 50 g.

## What is the mass of 3 moles?

3 moles of Oxygen atoms weigh 48.00 grams.

## What is the mass of 5.00 moles of water?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.

## How many moles are in 4g of oxygen?

Answer. To calculate the number of molecules in 4g of oxygen, we have, Moles of oxygen = 4/32 = 0.125mol, Molecules of oxygen = 0.125 * 6.022 * 10^23 = 7.52 * 10^22.

## What is the mass of one mole of water?

18.01528 g/mol

## How many moles of oxygen are produced?

The correct answer of this question is 5 moles of oxygen gas can be produced during the electrolytic decomposition of 180 g of water.

## How many moles of water will be produced if 14 moles of hydrogen are mixed with 7 moles of oxygen gas?

The numbers provided would create seven water molecules based on having fourteen hydrogen’s (which would be seven times the two required for water) and seven oxygen.

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
