How many moles does NO2 have?
Explanation: A substance’s molar mass tells you the mass of one mole of that substance. In your case, nitrogen dioxide, NO2 , is said to have a molar mass of 46.01 g/mol . That means that every mole of nitrogen dioxide will have a mass of 46.01 g .
How many moles are there in 69 g of NO2?
We just need to go ahead and calculate this and that will give us 3.14 moles off nitrogen. Okay, so in 69 g of nitrous oxide, there’s 3.14 g.
How many moles of nitrogen are in NO2?
Answer: 1.89 moles of nitrogen dioxide (NO2).
How many particles are in 7.5 moles?
Explanation: And Avogadro’s number , 6.022×1023⋅mol−1 specifies a molar quantity…… And so 7.5⋅mol×6.022×1023⋅mol−1≅4.5×1024 sulfur atoms .
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 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 do you convert moles to mass?
Multiply the molecular weight by the number of moles for the substance. The molecular weight is the number of grams per mole for the substance and gives the conversion factor for moles to grams for that particular substance. So, one mole of water has a mass of 18.02 grams (1 mol H2O x 18.02 g/mol = 18.02 g).
How do you convert KJ mol to KJ G?
As you know, this conversion factor is the molar mass of the given compound. In order to convert kilojoules per gram to kilojoules per mole, you need to multiply by grams per mole.
