U2.10 5000 kg of a hot solution containing 31 wt.% of Na,Co, is fed into a crystallizer. After cooling to 20C, Na,co, 10H,0 crystallizes out. The solubility of anhydrous sodium carbonate at this temperature is 21 kg per 100 kg of water. The water evaporating during crystallization makes up 5% of the initial solution weight. What is the amount of sodium carbonate decahydrate crystals? brate crustallized
