Mass in grams of 3 moles of nitrogen is 3 × 14 = 42 grams . Hence the correct answer is 42 grams.

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

The molar mass of nitrogen (N) is approximately 14.01 grams per mole of nitrogen atoms.

## What is the mass of 1 mol N?

(a) We know that the atomic mass of nitrogen is 14. Mass of one mole of nitrogen atoms is 14 g.

## What is the mass in grams of 2 moles of N?

Hence, 2 moles of nitrogen atoms weigh 28g.

## What is the mass in grams of 3 moles of O atoms?

3 moles of Oxygen atoms weigh 48.00 grams.

## What is the mass of N?

For nitrogen, the mass of the N_{2} molecule is simply (14.01 + 14.01) = 28.02 amu. This is referred to as the molecular mass and the molecular mass of any molecule is simply the sum of the atomic masses of all of the elements in that molecule.

## What is the mass of 0.1 mole of N atoms?

1 mole of nitrogen atoms is equivalent to the gram atomic mass of nitrogen. Therefore, 1 mole of nitrogen atoms contains 14 g.

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

Explanation: Normally 1 mole of F2 reacts with 1 mole of H2 giving 2 moles of HF (which is 20g).

## What is the mass of 5.5 mole of N2?

N2 has two atoms and atomic number OF Nitrogen is 7. so it`s molecular mass = 14 amu (7 protons and 7 neutrons) molecular mass of one mole of N2 = 28 gm/mole so mass of . 5 mole of N2 = . 5×28 gm = 14 gm.

## What is the mass of 1.5 moles of N2?

Answer: Mass of nitrogen in 1.5 gram / moles is 21 gram. Number of moles = Mass in gram / Molar mass. Given :– Molar mass of nitrogen = 14 a.m.u. Number of moles = 1.5 gram / moles. So , formula will change according to it.

## How many grams are in 1 mole of H?

By this definition, one mole of hydrogen is 2.016 grams, one mole of methane is 16.043 grams, and one mole of water is 18.015 grams. We can convert any gram quantity of a chemical substance to moles by dividing by its molecular weight.

## What is the mass of 3 moles of calcium atoms?

Therefore, $mass = 332.9g$ .

## How many grams are there in 3.5 moles of oxygen?

The atomic mass of oxygen is approximately 16 grams, however o2 would make it 32 grams. Then one would multiply 32 by 3.5 moles which would give you 112 grams per 3.5 moles. So,3.5 moles of oxygen has mass=3.5×16=56grams.

## How many atoms are in 3 moles of oxygen?

A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .
