Answer:
Explanation:
Given that,
Mass, m = 0.186 g
Volume occupies, V = 110 mL
We need to find the density of Nitrogen gas. The mass per unit volume is called density of an object. It is given by the formula as follows :
So, the required density is 
.

Pair Of Compounds that Are Isomers are CH3COCH3 and CH3CH2CHO. The answer is
number 4. Isomers have the same formula but different structures. In number 4,
both compounds contains three carbon atoms, one oxygen and 6 hydrogen atoms
that makes them isomers.</span>
Answer:
B. Add more chloride ions
Explanation:
Because we know based on lechatlier that any disturbance to equilibrium will make the shift act accordingly. If something is removed it wants to shift to side where it is removed to compensate for the change, if something is added it wants to move away from it to minimize the change.
Therefore, if you add chloride ions, the equilibrium shifts to left to make more solid lead chloride.
Density = Mass/Volume. Density = 64.5G/(34.2-25.0)ml = 7.01g/ml
