Explanation:
The mass of bromine is 79.904, and since there are two of them in the Calcium Bromide molecule, we'll multiply it by 2 to get 159.808. Dividing that by the full mass of the molecule then multiply it by 100 will give you the answer.

Answer:
2.956 moles chlorine gas will be produced
Explanation:
Step 1: data given
Number of moles carbon tetrachloride (CCl4) = 0.739 moles
carbon disulfide (s) = CS2(s)
chlorine (g) = Cl2(g)
carbon tetrachloride (l) = CCl4(l)
sulfur dichloride (s) = SCl2 (s)
Step 2: The balanced equation
CS2(s) + 4Cl2(g) → CCl4(l) +2SCl2
Step 3: Calculate moles chlorine gas
For 1 moles Cs2 we need 4 moles Cl2 to produce 1 mol CCl4 and 2 moles SCl2
For 0.739 moles CCl4 we need 4*0.739 = 2.956 moles Cl2
2.956 moles of chlorine gas will be produced
