To find the molar mass of calcium chloride (CaCl₂), first identify the atomic masses of its constituent elements: calcium (Ca) has an Atomic Mass of approximately 40.08 g/mol, and chlorine (Cl) has an atomic mass of about 35.45 g/mol. Since there are two chlorine atoms in calcium chloride, calculate the molar mass as follows: 40.08 g/mol (Ca) + 2 × 35.45 g/mol (Cl) = 111.98 g/mol. Therefore, the molar mass of calcium chloride is approximately 111.0 g/mol.

What is the molecular mass for calcium chloride?
Calcium chloride with formula CaCl2 has molecular mass of 141. Commercial calcium chloride has formula CaCl2,2H2O.It's molecular mass is 177.
How many moles of calcium are in 15.5 g calcium chloride?
If grams/molar mass=moles, then first the molar mass of the compound must be found. CaCl2 has a molar mass of 110.984. Divide the number of grams, 15.5, by 110.984, and you get the number of moles. Now, seeing as calcium is not diatomic like oxygen or chlorine, there needs to be no conversion between the number of moles of calcium in the compound and the number of moles of calcium outside of the compound. atoms, the number of calcium atoms in the compound divided by one mole of the compound will give us the ratio. Conveniently enough, that ratio is one calcium atom per molecule of calcium chloride, meaning that for every one mole of calcium chloride, 1 mole of pure calcium can be extracted. So once you find the number of mole of CaCl2, that is the number of moles of calcium as well. This may be a little difficult to grasp, but I'm sure that your teacher, if you're a student, will be able to explain why rather well.
What is is the molar mass of 3.00 of NaCL and 1.50kg?
The molar mass of NaCl (sodium chloride) is 58.44 g/mol. To find the molar mass of 3.00 mol of NaCl, you would multiply 3.00 mol by the molar mass of NaCl. For the 1.50 kg, you would first convert the mass from kilograms to grams (1 kg = 1000 g), then divide the mass by the molar mass to find the number of moles.
