# How Many Molecules Of Nitrogen Monoxide Are In A 22.5 Gram Sample?

So, nitric oxide has a molar mass of 30.01 g mol−1 , which means that one mole of nitric oxide has a mass of 30.01 g . Since your sample is about 8 g short of the mass of one mole, you can say for a fact that you're dealing with less than one mole of nitric oxide. Likewise, What is the mass of a nitrogen monoxide molecule in grams? Nitric oxide or nitrogen monoxide (NO) is a colorless gas. It has a boiling point (bp) of –151.8°C (at 1 atm) and molecular weight of 30.0 g mol1. Also Asked, How many molecules does nitrogen dioxide have? Answer and Explanation: In one mole of nitrogen dioxide (NO2 N O 2 ) there are therefore 6.02×1023 6.02 × 10 23 of particles or molecules. ## Similar Questions

### How many bonds does nitrogen monoxide have?

It typically forms 3 bonds and has a lone pair (:NH3) or makes 4 bonds with a positive charge (NH4+). Nitrogen is one of the few elements that readily forms strong multiple bonds.

### How do I calculate molar mass?

The molar mass is the mass of one mole of a sample. To find the molar mass, add the atomic masses (atomic weights) of all of the atoms in the molecule. Find the atomic mass for each element by using the mass given in the Periodic Table or table of atomic weights.

### How many moles are in carbon monoxide?

In CO there is one mole of Carbon and one mole of Oxygen so the number of atoms will be for two mols.

### How many grams do 4.3 x10 21 molecules of UF6 weigh?

So, dividing the number of molecules by Avogadro’s number gives us the number of moles. Multiplying that by the molecular weight gives us the mass. From the Periodic Table we find the gram-molecular weight of U to be238 and of F to be19. So, UF6 will have a gram-molecular weight of 352g.
