1 AnswerChemistry1 decade agoFind the initial volume and error?
Need to prepare a 150mL of 0.0010M solution of Fe(III). You obtain a 250+_0.1mL volumetric flask and a 10.0+_0.1 pipette. If the concetration of the stock solution is 0.0080
+_0.0001M, how much of this solution do you need to measure to prepare the final solution? assume you filled the flask with distilled water to the mark etched in the glass. Include a determination of the erron in the initial volume.
Please provide every helpful detail.
THANK YOU !
2 AnswersChemistry1 decade agohelp with chemistry error determination?
I have to find the final concentration
C1V1=C2V2
(0.500+_ 0.003M)(10.0+_0.1mL)=C2(100.00+_0.008mL)
Solving this I get C2=0.05
How do I find the error?
I figured this much out
[(0.003/0.500)+(0.1/10.0)+(0.08/100.00)] x 0.05=0.00084
I think I figured out the error. How much significan figures do I need? How will my final answer look like? is it 0.050+_ 0.001 ?
Please help and provide any helpful detail .

A 12.0 kg shell is launched at an angle of 55.0 degrees above the horizontal with an initial speed of 150 m/s. When it is at its highest point, the shell exploded into two fragments, one three times heavier than the other. The two fragments reach the ground at the same time. Assume that air resistance can be ignored. If the heavier fragment lands back at the same point from which the shell was launched, where will the lighter fragment land? Please explain
