1.56g Chloral Hydrate will contain 1g Cl
500 moles of Carbon weighs 6 Kg
We're going to be using this formula a lot for these questions;
Number of moles =
Number of molecules in a mole = 6.023x
Molar Mass (
Number of moles of Chloral Hydrate = Mass/Molar Mass
= 0.0302.... moles.
Number of molecules of Chloral Hydrate = 6.023x
3 atoms of chlorine per molecule of chloral hydrate.
Therefore, number of atoms of chlorine = 1.821...x
Number of moles of Chlorine atoms in 1g = 1/35.45 = 0.0282... moles
One molecule of chloral hydrate contains three chlorine atoms, therefore 1/3 of 0.0282... moles of chloral hydrate molecules are needed.
Number of moles of Chloral Hydrate needed =
Mass = Number of moles x Molar Mass = 9.4029...x
Mass of 500 moles of Carbon = 500 x 12 = 6000g = 6 Kg
