## How many moles is 153.4 g of ammonia?

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).

## What is the number of moles in ammonia?

1 mol of nitrogen has a mass of 28.02 g, while 3 mol of hydrogen has a mass of 6.06 g, and 2 mol of ammonia has a mass of 34.08 g. Mass and the number of atoms must be conserved in any chemical reaction.

## How many moles are in 50 grams of ammonia?

We have 50 g of nitrogen gas here, so we need to find the number of moles of nitrogen. From here, we would produce 1.79⋅2=3.58 moles of ammonia.

## How many moles are in 5.1 g of ammonia?

Molar mass of ammonia is 17.031 g/ mol. Therefore, 5.1 grams of ammonia is 5.1÷17.031 moles =0.2993845 moles (=apprx 0.3 moles).

## How many moles are in 20g of NH3?

Dimensional analysis: (20g NH_{3}) * (1 mole NH_{3} / 17.0g NH_{3}) = 1.1_{8} ≅ 1.2 mole NH_{3} (2 sig figs). (1.18 mole) * (6.022 x 10^{23} molecules/ 1 mole) = 7.1 x 10^{23} molecules.

## How many grams are in a mole of N2?

That means that a mole of N2 has a mass of 28 grams.

## How many molecules of ammonia are in 2.0 moles of ammonia?

What is the mass of this quantity of ammonia, and in terms of moles, how many atoms we got here? So first we calculate no of molecules in 2 moles of NH_3 . So we have 2×6.022×10 molecules of = 12.044×10 molecules. Thanks!!!

## How many grams are in one mole of ammonia?

17.03052 g/mol .

## How many grams are in 2 moles of NH3?

The molecular weight of NH3 is 17. (14+1+1+1). So 1 mole of ammonia weighs 17 grams. Therefore 2 moles will weigh 34 gram.

## 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 many moles are in 75 grams of calcium?

There are 0.75 moles.

## How many moles of ammonia are present in 100 grams of ammonia?

The answer is 17.03052. We assume you are converting between grams Ammonia and mole.

## How many moles of NH3 molecules are there in 6.8 g NH3?

Thus correct answer is 0.5 moles.

## How many moles are in 68 grams of NH3?

Converting the mass, in grams, of a substance to moles requires a conversion factor of (one mole of substance/molar mass of substance).
