if the solubility of NaCl is 32 g per 100 g of water at 25*C,how many grams could be dissolved in 200 g of water at 25*C?
Solubility of NaCl at 25C0 = 32g/100g
Mass of water = 200g
Mass of NaCl = ?
Mass of NaCl = (32*200)/100
Mass of NaCl = 64g
At 70*C the solubility of KCl is 40 g per 100 g of water,how many grams could be dissolved in only 50 g of water?
Mass of KCl = (40*50)/100
Mass of KCl = 20g
