What is the mass of 0.425 moles of CaCl2? The molar mass of CaCl2 is 110.98 g/mol.
g = moles x molar mass
To find the mass of 0.425 moles of CaCl2, you need to multiply the number of moles by the molar mass of CaCl2.
First, find the molar mass of CaCl2 by adding up the atomic masses of calcium (Ca) and chlorine (Cl).
The atomic mass of Ca is 40.08 g/mol, and the atomic mass of Cl is 35.45 g/mol. Since there are two chlorine atoms in CaCl2, multiply the atomic mass of Cl by 2.
So, the molar mass of CaCl2 is calculated as:
40.08 g/mol (Ca) + 2(35.45 g/mol) (Cl) = 110.98 g/mol
Now, to find the mass of 0.425 moles of CaCl2, multiply the number of moles by the molar mass:
0.425 moles x 110.98 g/mol = 47.09 grams
Therefore, the mass of 0.425 moles of CaCl2 is 47.09 grams.
