Calculate the mass of 0.5 mole of N2 gas (mass from mole of molecule). mass of one mole of nitrogen gas is 28 gram(14*2) mass of 0.5 mole of nitrogen is 14 grams.

## How do you find the 0.5 mole of N2 gas?

1 Answer

- 1 mole of N
_{2}= Gram molecular mass of N_{2} - Or 1 mole of N
_{2}= 28 gm. - ∴ 0.5 mole of N
_{2}gas = 0.5 × 28. - = 14 gm of N
_{2}

## What is the mass of 0.5 mole of N atom?

The mass of 0.5 mole of nitrogen atom is 7 g.

## What is the mass of 0.5 mole of?

(Atomic masses : H = 1 u, O = 16 u) Thus, the mass of 1 mole of water is 18 grams. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## What is the mass of 5.0 molecules of N2?

1 Answer. Meave60. Aug 17, 2017. The mass of 5.00×1023 molecules of N2 is 23.3 g N2 .

## What is the mass of 0.2 mole of n2?

Mass of nitrogen gas= 14gram. 0.2 moles= 14×0.2. = 2.8gram.

## How do you find the mass of n2?

How many liters of N gas are in 2.4 moles at STP? We know that 22.4 liters of a gas at STP equals one mole, 2.5 moles of the gas will take up 22.4 * 2.5 liters of volume which is equal to 56 liters. How many grams are in 22.4 liters of nitrogen? At STP, one mole of any gas occupies 22.4 litres.

## What is the mass of 0.5 mole of NH3?

Hence the mass of 0.5 moles of NH3 = 17/2 u (OR) 8.5 u.

## How many nitrogen atoms are there in 0.5 moles of nitrogen?

6. 022×1023 atoms.

## What is the mass of O 5 mole of water?

The molecules of water have hydrogen bonding and thus, for another substance to be soluble in water molecules shall form hydrogen bond with water. Mass of 0.5 mole of water is 9g.

## What is the mass of O 5 mole of water molecules?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

## What is the mass of 0.2 mole of water molecules?

The mass of 1mole of water =18gms. Than, the mass of 0.2moles of water=x. Now x=18×0.2=3.6gms.

## How much does 1 mole of N2 weigh in Gram?

1 mole is equal to 1 moles N2, or 28.0134 grams.
