(0.50M)(3.50mL) = c2(75.00)
c2= 2.3e2
Is this correct?

Amanda Mosley
Yes this appears to be

Hannah
What about (0.50)(1.75) = c2(75.00)
c2=1.16e2.
Is this correct in terms of correct number of sig figs? 
Amanda Mosley
Ok try the problem again then comeback something is off you sisnt multiply incorrectly did you

Hannah
I got 0.011666667 so for correct sig figs is that 1.16e2 or 1.1e2?

Amanda Mosley
1.1e it diesnt have six in the answer

Hannah
So are you saying that's not the answer????
