Answer:
<em>(B.) What is the molar solubility of barium chloride, BaCl2 in water? </em>
Explanation:
Molar solubility is the number of moles of a substance that can dissolve in a liter of solution to the point of the solution's saturation. It can be calculated stoichiometrically from a substance's solubility product constant in mol/L.
Since all the
reacted all the
from the information, we can easily assume all the substances were consumed in the reaction, and hence account for their purity. Furthermore,
is insoluble in water, the most probable scientific query would be the molar solubility of the
used in the experiment.
Answer : The correct option is, 0.961 g/ml
Solution : Given,
Mass of sample = 35.4 g
Volume of sample = 36.82 ml
Formula used :

Now put all the given values in this formula, we get the density of the sample.

Therefore, the density of the sample is, 0.961 g/ml
Answer:
130.5g
Explanation:
At the of the reaction, the combined mass of X and Y will be 130.5g.
The premise for this conclusion is based on the law of conservation of matter.
This law states that "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
In essence, in a chemical reaction, there is no mass loss.
- The amount of product in the reaction is expected to be the same as the amount of reactants used in the experiment.
- When we start with 130.5g then we should end with 130.5g
