Well if the atomic weight of chlorine gas is 70.906, that means one mole of it is going to have a mass of 70.906 grams. So for every mole, we have 70.90 grams, we have . 07 moles, so we’ll multiply .
How do you calculate moles of chlorine?
The mass of one mole of chlorine gas is its molar mass, and can be determined by multiplying its subscript by the molar mass of chlorine (atomic weight on the periodic table in g/mol), which is 35.45 g/mol .
How much is a mole of chlorine?
One mole of chlorine weighs 70 grams. Just like a dozen equals twelve, a mole equals Avogadro’s number of atoms or 6.02 × 1023.
How many moles are there in Cl2?
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 grams are in 3 moles of chlorine?
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Chlorine, or 35.453 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Chlorine and gram.
How do I calculate moles?
Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.
How many moles of chlorine are in 100g chlorine?
1 grams Chlorine is equal to 0.028206357713029 mole.
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.
