U2.10 5000 kg of a hot solution containing 31 wt.% of Na,CO, is fed into a crystallizer. After cooling to 20°C, 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?
