The correct equilibrium expression would be one that has products over reactants, and to the power of their stoichiometric coefficient. Also, it would not include any liquids or solids.
The equilibrium expression for your balanced reaction is:
![\Large K_c = \sf{\frac{[SO_3]^2_{equil}}{[SO_2]^2_{equil}[O_2]^2_{equil}}](https://tex.z-dn.net/?f=%5CLarge%20K_c%20%3D%20%5Csf%7B%5Cfrac%7B%5BSO_3%5D%5E2_%7Bequil%7D%7D%7B%5BSO_2%5D%5E2_%7Bequil%7D%5BO_2%5D%5E2_%7Bequil%7D%7D)
The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water. What is the exact change in volume of the water when it freezes as ice? Example: Calculate the volume in a 100 g ice cube with a density of 0.92 g per mL.
Answer:
Density, 
Explanation:
Mass of a marble slab is 38.6 kg 38600 grams
The dimensions of the marble is 17 cm×23 cm×4 cm
We need to find its density. Mass per unit volume equals density. So,
So, the density of the marble slab is
