Question

Determine the number of moles of Cl in 1.6 mol CaCl2.

Express your answer using two significant figures.

Answer 1

Answer 2

To determine the number of moles of chlorine (Cl) in 1.6 moles of calcium chloride (CaCl₂), follow these steps:

1. Understand the formula:
   CaCl₂ contains 1 calcium (Ca) atom and 2 chlorine (Cl) atoms.

2. 
   

3. Calculate moles of Cl:
   Since each mole of CaCl₂ has 2 moles of Cl, multiply the given moles of CaCl₂ by 2:

   $$1.6\text{ mol CaCl₂}\times 2=3.2\text{ mol Cl}$$

5. Final answer:
   The number of moles of Cl is 3.2 (rounded to two significant figures).

So, there are 3.2 moles of chlorine in 1.6 moles of CaCl₂
