Let "x" be the number of pages Nora used for science.
Nora used x + 21 pages for math.
She used x + 14 pages for language.
The total number of pages used is x + (x + 21) + (x + 14) = 3x + 35.
Given that she used 78 pages for math, 3x + 35 = 78.
Subtracting 35 from both sides, we get 3x = 43.
Dividing both sides by 3, we get x = 43 / 3 = <<43/3=14.333333333333334>>14.33 pages.
Therefore, Nora used 14.33 + 14 = <<14.33+14=28.33>>28.33 pages for language. Answer: \boxed{28}.
