Technically one cannot calculate a normality without knowing the reaction.
USUALLY K2Cr2O7 goes to 2Cr^3+.
So equivalent weight K2Cr2O7 = molar mass/6 = 294.18/6 = 49.03. I don't expect you will have seen this equation but keep it in mind; it can help you many times in the future.
mL x N x milliequivalent weight = grams.
You know mL, N, and mew; solve for grams.
