Answer :
Answer: 110 g/mol
Explanation: first find the molar mass of CaCl2 using the periodic table:
Ca: 40
Cl: 35 (Since Cl has a 2 at the end, multiply 35 by 2)
70+40= 110
Then multiply by amount of moles
110g×1.000mol = 110 g/mol
The mass of 1.000 mole of CaCl₂ is 111 grams.
How to calculate the mass of substance ?
To find the mass of substance multiply the number of moles by its molecular weight.
Mass of substance = Number of mole × Molecular weight
How to find the molecular weight of compound ?
Molecular weight of CaCl₂ = Atomic weight of Ca + 2 × Atomic weight of Cl
= 40 + 2 × (35.5)
= 40 + 71
= 111 g/mol
Now put the value of molecular weight in above formula we get
Mass of substance = Number of mole × Molecular weight
= 1.000 mol × 111 g/mol
= 111 grams
Thus, from above conclusion we can say that The mass of 1.000 mole of CaCl₂ is 111 grams.
