# What is the mass number of nh3?

## What is the mass number of nh3?

17.0306g.
Ammonia’s molecular formula is NH3. Its molar mass is 17.0306g.

### What is the mass of 4 moles of NH3?

#### How many moles are in NH3?

Since molar mass of NH3 is 17 (14+1×3) one mole contains 17 gram. Hence 9 moles are present in 153gm(153/17=9). Molar mass = mass of the one mole of the substance .

What is the mass of 5 moles of NH3?

Mass of ammonia = number of moles × gram-molecular mass = 5×17g=85g 5 × 17 g = 85 g .

What is the mass of 5 moles of ammonia?

Therefore, the mass of 5 mole of ammonia is 85 gm.

## What is the mass of 2 moles of NH3?

34.08g.
1mol of nitrogen has a mass of 28.02g, while 3mol of hydrogen has a mass of 6.06g, and 2mol of ammonia has a mass of 34.08g.

### What is the molar mass of Na?

22.989769 u
Sodium/Atomic mass

#### What is the mass of 7 moles of ammonia?

Selina – Chemistry – Class 7 Molecular weight= 17. Step 2. Wt in gm = moles ×molecular wt. Final answer is 11.9 is the mass of 0.7 moles of ammonia.

How do you calculate the percent by mass of NH3?

To find the percent composition (by mass) for each element in NH3 we need to determine the molar mass for each element and for the entire NH3 compound.We’ll

Is NH3 more polar than PH3?

Yes, NH3 is more polar than PH3 . Because in NH3 the Electronegativity of nitrogen atom is more than hydrogen atom so , the dipole direction is from hydrogen to nitrogen and lone pair too have dipole parallel to all the dipoles of N and H atoms . Hence all the dipole add up and dipole moment is more .

## What is the molecular weight of NH3?

›› NH3 molecular weight. Molar mass of NH3 = 17.03052 g/mol. This compound is also known as

### What is the percent of N in NH3?
