## What is the mass of 0.5 mole of chlorine gas?

So, weight of 0.5 moles of chlorine is 0. 5×71=35.

## What is the mass of 1 mole of chlorine gas?

For example: Chlorine exists as Cl2 in nature. Its molar mass would be (35.45 x 2) grams per mole, or 70.9 g/mol.

## How many atoms are there in 1 mole of chlorine?

A mole contains 6.022 × 10 23molecules, but each molecule of chlorine gas contains two atoms. A mole is one gram molecular weight. In 1 mole chlorine there are 2 chlorine atoms.

## What will be the mass of 0.5 mole of n2 gas?

therefore mass of 0.5 moles of N₂ = 14 grams .

## What is the mass of 2.5 mole of Cl2?

Answer: Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71. Gram.

## What is the volume of 0.0056 moles of chlorine molecules?

Calculate the volume of 0.0056 moles of chlorine molecules. volume of 0.0056 moles of Cl2 = 0.0056 mol x 24 dm3mol-1 = 0.1344 dm3 = 134.4 cm3 7 Page 8 Example 3 Calculate the number of moles of hydrogen molecules in 240 cm3 of the gas.

## What is the mass of 0.2 mole of chlorine gas?

Chlorine gas Cl 2, has a relative molecular mass of 71 because it is made up of two Cl atoms, each of Mr 35.5. A mole of chlorine gas has a mass of 71g, and contains two moles of chlorine atoms, each of mass 35.5g.

## What is the formula of chlorine gas?

Properties Of Chlorine Gas Formula

## What does one mole of oxygen weigh?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.

## How much does 1 mole of 1h weigh?

1 Expert Answer

These numbers are either in atomic mass units (amu), or in grams per mole of atoms. This means that 1 MOLE of hydrogen atoms will weigh 1.008 grams.

## How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How many molecules is 0.5 moles?

A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water. 0.5 x 6.022 x 10^23 molecules of water.

## What is the mass of 5 moles of nitrogen gas?

Answer. Molar Mass of N2 is 28.

## What is the mass in gram of 0.5 mole of S?

One mole of sulphur contains 32 amu. so 0.5 mole will have 16 amu.
