How many moles are in CaCl2 2H2O?
Calculate how many moles of CaCl2•2H2O are present in 1.50 g of CaCl2•2H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl2•2H2O.
|Initial: CaCl2 x 2H20 (g)||1.50 g|
|Initial: CaCl2 (mol)||0.0102 mol|
|Initial: NaCO3 (mol)||106 g/mol|
|Initial: NaCO3 (g)|
|Theoretical: CaCO3||1.02 g|
What is the weight of 2 mole of water?
One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
