## How do you calculate moles of chlorine?

1 mole of chlorine gas is Cl2=2×35.5g=71g=Grammolecularweight. Gram molecular weight is the mass in grams of the substance numerically equal to its molecular weight, chlorine is a halogen, and an elemental gas, and occurs as Cl2.

## What is the mole equation?

Worked Example: moles = mass ÷ molar mass (n=m/M)

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

## How many moles are in 50 grams of co2?

Explanation: The answer is 44.0095.

## How many liters are in a mole?

As long as the gas is ideal, 1 mole = 22.4L.

## What is the volume of 2 moles of chlorine at STP?

At STP, the molar volume of all gases is 22.4dm3/mol . Hence 2mol of Cl2 at STP occupies a volume of 44.8dm3 .

## What is the mole 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).

## How do I calculate moles?

How to find moles?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.

## How many grams are in 3 moles of chlorine gas?

So the mass is 213 grams. So, the mass of 3 moles of chlorine molecule is 213gram.

## Why is mole concept important?

The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. … Defining the mole in this way allows you change grams to moles or moles to particles.

## What are the units of mole?

The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 x 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in the unit mol1 and is called the Avogadro number.

## How can I calculate weight?

Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
