# How many grams are in 3 moles of N2?

Contents

We are given with the moles of nitrogen (N) is 3 moles. Molar mass of nitrogen is 14 amu or 14 grams. Thus 28 grams of nitrogen occupies 22.4 litres at STP and is 1 mole. Mass in grams of 3 moles of nitrogen is 3 × 14 = 42 grams .

## What is mass in grams of 3 moles of N2?

Molecular weight of N2​=28g. ∴ 1 mole of N2​ weighs 28gm. ∴ 3 moles of N2​ weighs =3×28g=84g.

## How many grams are in 2 moles of N2?

14.01 g/mol is molar mass for Nitrogen (N), thus 28.02 g/mol N2.

## How many gram moles of N2 does it contain?

The answer is 0.035697202053303. We assume you are converting between moles N2 and gram. You can view more details on each measurement unit: molecular weight of N2 or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles N2, or 28.0134 grams.

## How many grams are in HNO3?

The molar mass of HNO3 is 63.02 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 many grams are in 2 moles of NaBr?

Start with given, which is 2.20 moles of NaBr. We use total molar mass of NaBr to convert from moles of NaBr into grams of NaBr. 22.99+79.90= 102.89 g/mol NaBr. So, there is 226.36 grams of NaBr in 2.20 moles of NaBr.

## 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 .
