To determine the grams of compound that would dissolve in 200ml of water at 40°C, we need to know the specific solubility of the compound in water. Solubility is typically given in terms of grams of solute (compound) that can dissolve in a specified amount of solvent (water).
Once we have the solubility value, we can use it to calculate the grams of compound that would dissolve in 200ml of water. Here are the steps to follow:
1. Look up the solubility of the compound in water at 40°C. Solubility values are often given in grams of solute per 100ml of water. Let's assume the solubility is given as 10g/100ml of water.
2. Calculate the solubility of the compound in grams per 1ml of water. To do this, divide the solubility value by 100: 10g/100ml ÷ 100 = 0.1g/1ml.
3. Multiply the solubility in grams per 1ml by the volume of water used (200ml) to find the grams of compound that would dissolve in 200ml of water: 0.1g/1ml × 200ml = 20 grams.
Therefore, if 200ml of water were used instead of 100ml, and assuming the solubility is 10g/100ml, 20 grams of the compound would dissolve at 40°C.
