What is the mass percentage of 28.7 g of boric acid in a 47.5 g solution?

The overall chemical reaction for photosynthesis isshown below: 6co2 + 6h20 → c6h12o6 + 602what mass of glucose (c6h1206) can form from71.89 g co2? (molar mass of c6h1206 = 180.18g/mol; molar mass of co2 = 44.01 g/mol)71.89 g co2=g c6h1206

Which is mostly likely why many scientists reject the cold fusion theory
