Hi everybody,
If a solution A contains 100mg of quanine sulfate and it dissolved in 100ml of 0.5M of sulfuric acid and the second solution, solution B was made up by diluting 10ml of solution A using 0.5M sulfuric acid and made up 100ml, calculate the new concentration.
Using this value, solution C was made up by diluting 10ml of solution B and made it up to 25ml, calculate the new concentration for solution C.
Thank you
