Answer: b. 4.8 g
Explanation:
Given : 5 carats = 1 gram
Thus if 5 carats is equivalent to = 1 g
24 carats is equivalent to = 
Thus 4.8 grams of gold are contained in a 24-carat gold chain.
The eagle is not a producer its a consumer
Missing in your question the K constant value =2.99X10^-7
The reaction equation:
SOCl2 ⇄ SO2 +Cl2
initial 0.195 0 0
-X +X +X
final (0.195-X) X X
K= [SO2][Cl2]/SOCl2
by substitution
2.99X10^-7 = (X)(X)/(0.195-X)
2.99X10^-7 = X^2 / (0.195-X) by solving this equation
∴X = 0.00024 = 2.4 X10^-4
∴[Cl2] = 2.4X10^-4 m
