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

The molar mass of chlorine is \$35.45\$ g/mol. So, the moles of the chlorine is \$0.20\$ mol. According to the Avogadro, one mole of any substance contains\$,6.02 times {10^{23}}\$ atoms, molecules or ions of that substance.

## What is the mass of 1 mole Cl2?

One mole of chlorine mass 70 grams. Just like a dozen equals twelve, a mole equals Avogadro’s number of atoms or 6.02 × 10^23.

## How do you find the number of molecules in 1 mole?

Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.

## When 0.1 mole of atoms of an element reacts with chlorine?

when 0.1 mole of atoms of an element react with chlorine there is an increase in mass of 7.1 g. The chloride has a high melting point.

## How many atoms are in 1g of Cl2?

1g of Cl2 has 1.67 x 10²² atoms.

## How many molecules are there in Cl2?

Hence, the answer is 3.33⋅1023 molecules of Cl2. Note that 6.022⋅1023 is also known as Avogadro’s number, and it can be referred to as the number of molecules in one mole of that substance. Also, I calculated 70.9 because 35.45 g/mol (the mass of one Chlorine atom) times 2 is 70.9 g/mol (Cl2 has two Chlorine atoms).

## What is the mass of 2 moles 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.

## How many molecules are there in 1 mole of water?

For example: H2O has two hydrogens and one oxygen. The atomic mass of hydrogen is 1.0078 and the atomic mass of oxygen is 15.999, so the mass of a mole of water is 2 x 1.0078 + 15.999. Therefore, a mole of water, or 6.022 x 1023 molecules, weighs 18.0146 grams.
