Actually, the formula is pH+=+-log%2810%2Cx%29
pH = 9.3
pH+=+-log%2810%2Cx%29
9.3+=+-log%2810%2Cx%29
-9.3+=+log%2810%2Cx%29
10%5E%28-9.3%29+=+x
10%5E%28-3%2F10%29+X+10%5E%28-9%29+=+x
%281%2F10%5E%283%2F10%29%29+X+10%5E%28-9%29+=+x
%281%2F10%5E%283%2F10%29%29+X+10%5E%28-9%29+=+x
0.50119 X 10^(-9) = x
5.0119 X 10^(-10) = x Answer: D)
