The mass of NO₂ for 3.45 number of moles are 158.7 grams.
What is Mole ?
The mole, symbol mol, is the SI base unit of amount of substance.
The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample.
To calculate the mass for given number of moles ;
we use the equation :
n (Mole) = given mass / Molecular mass
Given :
- Moles of nitrogen dioxide = 3.45 moles
- Molar mass of nitrogen dioxide = 46 g
Putting values in above equation, we get :
3.45 = mass of NO₂ / 46
Mass of NO₂ = 158.7 g
Hence, the mass of (NO₂) nitrogen dioxide for given number of moles are 158.7 grams.
