# Frequent question: What is the mass of 2 5 moles of chlorine gas?

Contents

## What is the mass of 2.5 mole of chlorine gas?

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 mass of 0.2 moles of chlorine?

Therefore, 0.2 moles of chlorine to grams is the same as 0.2 moles of Cl to grams, 0.2 moles of chlorine to g, and 0.2 moles of Cl to g. Furthermore, the atomic mass of chlorine is 35.453. That means that one mole of chlorine weighs 35.453 grams (35.453 g/mol).

## What is the mass of 2.5 moles of co2?

2.5 mole of co2 = 2.5 x 4.4 = 11g.

## How many molecules are in 2 moles of chlorine gas?

A mole is a unit of measurement, which equals 6.02 * 10^23. If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.

## What volume will 2.5 moles of a gas occupy 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 1.50 moles of Cl 2?

Explanation: Atomic weight of chlorine is 35.45 g/mol, but chlorine gas exists as a diatomic molecule, so molar mass is 70.9 g/mol. Therefore 1.50 moles will have a mass of 1.50 x 70.9 = 106.35 g.

## What is the mass of 0.5 mole of water molecules?

Mass of 0.5 mole of water is 9g.

## What is the molar mass of chlorine gas?

## How many molecules are in 2.5 moles?

1.5×1024 molecules.

## What is the mass of 2.75 moles of CO2?

The mass of CO2 is [44.0 g/mol × 2.75 moles] = 121 grams. Therefore, the mass of 2.75 moles of CO2 is 121 grams.

## What is the mass of 2 moles of Ca Oh 2?

The molar mass of calcium hydroxide, Ca(OH)2 , is 74.092 g/mol .

## How many grams are in 2 moles of Cl2?

The molecular weight of chlorine (Cl2) is 2×35.5 = 71, so the mass of two moles of chlorine gas is 2×71 g = 142 grams.

## What is the molar mass of fe2o3?

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).
