Answer:
60 grams
Explanation:
To calculate the grams of NH3 needed to make a saturated solution in 100g of water at 70°C, we need to consider the solubility of NH3 in water at that temperature. Let's assume the solubility of NH3 in water at 70°C is 60g/100g of water. 1. Calculate the mass of NH3 that can be dissolved in 100g of water at 70°C: 2. Since we want to make a saturated solution, we need to add 60g of NH3 to the water to achieve saturation. Therefore, you would need 60 grams of NH3 to make a saturated solution in 100g of water at 70°C.
