I'm pretty sure this is correct :) 

calculate the volume of the brass piece: 

(145 g over x) = 8.56 g/cm^3 

solve for x, then add that volume to the 50.0 mL and that will be the volume after the brass piece is added to the water. 

<span>Oh and by the way, you can add the two values even though one is in mL and one is in cm^3. This is because 1 mL = 1 cm^3</span>

I'm not very good at chemistry, but I would say 158.56. I may be wrong, answer at your own risk.

25 mL of a concentrated solution of sodium chloride is added to a 500 mL volumetric flask and sufficient water added to make up
Dima020 [189]

Answer:

2.5 M

Explanation:

To address this question, we can use the dilution formula:  

M1V1= M2V2

Where M1 is the concentration of the concentrated solution  

V1 is the volume of the concentrated solution (the amount of mL that we                            take from the initial solution)  

        M2 is the concentration of the diluted solution  

V2 is the volume of the diluted solution or the final volume.  

For this case, we know V1, M2 and V2 and we want to know M1.  

Following the formula, M1=  \frac{V2*M2}{V1}

Therefore, M1 =  \frac{(500)*(0.125)}{25}

For this, the  concentration of the original solution is 2.5 M.

I hope this clarifies your inquiry.

Solutions, _____ colloids, _____ light.
soldi70 [24.7K]

Answer: unlike, will not scatter

Explanation:

Colloids are unlike solutions because their dispersed particles are much larger than those of a solution. The dispersed particles of a colloid cannot be separated by filtration, but they scatter light, a phenomenon called the Tyndall effect.
