Molarity =wt/M.wt * 1000/V
=> 1.77 = wt/180 * 1000/555
> wt = 1.77 * 180*555 /1000 = 176.823 g
Answer: C) The concentration of HI will increase as the system approaches equilibrium.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for 
is written as:
![Q_c=\frac{[HI]^2}{[H_2]^1[I_2]^1}](https://tex.z-dn.net/?f=Q_c%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5E1%5BI_2%5D%5E1%7D)
Thus as 
, the reaction will shift towards the right i.e. towards the product side.
There are 4 energy sublevels are present in the principal energy level n = 4.
<h3>What is sublevels?</h3>
Sub-level is a type of level that is lower than another level or it is a part or component of a big level. S, p, d and f are the four energy levels in which electrons are present.
So we can conclude that 4 energy sublevels are present in the principal energy level n = 4.

Jupiter and Saturn has ammonia clouds in its atmosphere since the molecules of ammonia gas that are present in their atmospheres condense to form clouds. However, these ammonia clouds are more visible in Jupiter than in Saturn because of their lower altitude in Saturn.
Since the orbital speeds are slower for planets with larger orbits, we can arrange the planets by their orbital speeds from the slowest to the fastest: Saturn<Jupiter<Mars<Mercury
