Using the equation below, calculate the percent yield of H3PO4 if an experiment that started with 12.98 grams of HCl and excess Na3PO4 yielded 8.42 g of H3PO4. Please round to the nearest 0.01 and remember units and substance. Na3PO4 + HCl --> NaCl + H3PO4

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4
