i did it and used 6.2E-10. my answer wasn't there so i was wondering if i did something wrong..i got 7.11 for pH
The problem didn't include Ka
i got 11.5 but im not sure because the problems i did before i had to change to ka first and that was the pH and got those answers right...but i don't understand why i have to do it this way though its the right way...quest is saying its wrong..

in the gravimetric determination of barium in BaCrO4, what weight of sample must be taken so that the weight of the precipitate in milligrams multiplied by 100 will equal the % Ba in the sample?
Difference between initial and final perchlorate(18.6137-18.6448) = 0.0311
ascarite(16.8425-16.9098)= 0.0673
%H= (0.0311x2x1.00784/44.00766)/947.4×100= 0.000150355
%C=(0.0673x12.0096/44.0076)/947.4x100=0.001938572
0.000150355x1mol/1.00784= 0.000148866
0.001938572x1mol/12.01= 0.000161413
0.000148866÷0.000148866= 1
0.000161413÷0.000148866=1.08
1×2= 2
1.08×2= 2.17
