<span>density is an intensive property of the matter, it doesnt change with the change of mass for the same substance, at the same pressure and temperature</span>
When the pressure is increased, the equilibrium will shift to the left to offset the pressure increase. Equilibrium shifting to the left side is favored because the left side has fewer moles of gas than the number of moles of gas on the right-hand side and because it exerts less pressure. Therefore, the answer is there will be a shift toward the reactants.

Answer:
Amount left after 140 days is 38.125 g.
Explanation:
Given data:
Half life of Co-59 = 35 days
Total mass of sample = 610.0 g
Sample remain after 140 days = ?
Solution:
Number of half lives passes during 140 days:
Number of half lives = T elapsed / Half lives
Number of half lives = 140 days / 35 days
Number of half lives = 4
Amount left:
At time zero = 610 g
At first half life = 610 g/2 = 305 g
At second half life = 305 g/2 = 152.5 g
At 3rd half life = 152.5 g/2 = 76.25 g
At 4th half life = 76.25 g /2 =38.125 g
Amount left after 140 days is 38.125 g.
M₀(CO₂)=8.8*10² g
m(LiOH)=3.5*10⁴ g
x=9 d
2LiOH + CO₂ = Li₂CO₃ + H₂O
m(CO₂)=M(CO₂)m(LiOH)/2M(LiOH)
N=m(CO₂)/xm₀(CO₂)=M(CO₂)m(LiOH)/{2M(LiOH)xm₀(CO₂)}
N=44.01*3.5*10⁴/{2*23.95*9*8.8*10²}=4
The maximum number of people is 4.
It is also possible the reaction:
Li₂CO₃ + CO₂ + H₂O = 2LiHCO₃
