The question is incomplete, here is the complete question:
The solubility of substance X in water at a certain temperature is 35.7 g /100. g. Suppose that you have 330.0 g of substance X. What is the minimum volume of water you would need to dissolve it all? (Assume that the density of water is 1.00 g/mL.)
<u>Answer:</u> The minimum volume of water that would be needed is 940.17 mL
<u>Explanation:</u>
We are given:
Solubility of substance X in water = 35.1 g/100 g
This means that 35.1 grams of substance X is dissolved in 100 grams of water
Applying unitary method:
If 35.1 grams of substance X is dissolved in 100 grams of water
So, 330.0 grams of substance X will be dissolved in = 
of water
To calculate the volume of water, we use the equation:
Density of water = 1 g/mL
Mass of water = 940.17 g
Putting values in above equation, we get:
Hence, the minimum volume of water that would be needed is 940.17 mL

Answer: all of those are the right choices. :) promise
Explanation:
Answer:
Volume = (0.62 m)^3
Explanation:
If the density of silver is 10.5 g/cm, the volume of the silver is (0.62 m)^3.
Answer:
The solution's new volume is 1.68 L
Explanation:
Dilution is the procedure to prepare a less concentrated solution from a more concentrated one, and simply consists of adding more solvent. So, in a dilution the amount of solute does not vary, but the volume of the solvent varies.
In summary, a dilution is a lower concentration solution than the original.
The way to do the calculations in a dilution is through the expression:
Ci*Vi=Cf*Vf
where C and V are concentration and volume, respectively; and the i and f subscripts indicate initial and final respectively.
In this case, being:
- Ci= 7 M
- Vi= 0.60 L
- Cf= 2.5 M
- Vf=?
Replacing:
7 M*0.60 L= 2.5 M* Vf
Solving:
Vf= 1.68 L
<u><em>The solution's new volume is 1.68 L</em></u>
