0.6g of copper sulfate pentahydrate is diluted into a 100mL volumetric flask, from which about 10 mL of solution is pipetted into another 50mL volumetric flask to be diluted. What is the final concentration of this solution? The molar mass of copper sulfate pentahydrate is 249.69g/mol. The final answer should be 4.806x10^-3 M. Please show all your work, thank you.
Find the concentration (molarity) of an aqueous solution prepared by dissolving 10g of NaOH(s) in 100mL of water. Find the concentration (molarity) of a NaOH solution that contains 5g of NaOH and 1000 mL of water. What is the new concentration when we add 1L more of water to the prepared solution in question (2).? If you have 10 ml of a 5M solution of NaOH, how many mol of NaOH you have? How many mol of Na+ you have?...

Amadeo quantitatively transferred a precise mass of potassium dichromate to a flask. He swirled the flask after filling the flask halfway with deion calibration mark. Then he diluted to the mark, adding water above the calibration mark. How would Amadeo's calculated K2Cr20 molarity compare to the actual value? Explain. (Hint: Write the generic calculation (no numbers needed) and show where and how the calculation is affected).
please help me! i just need instruction on how to do the first one
for both problems. you dont need to do every flask. i included the
data

5. Explain how an Am-Be neutron source works. Write down the complete reaction equation, calculate the Q-value and maximum neutron energy for the (a, n) reaction involved. Is there a threshold energy for this (a, n) reaction, and if so what is it?
Please explain the difference between a secondary source and a primary source.
