Answer:

640 grams

Step-by-step explanation:

look up Solubility table in wikipedia for potassium nitrate (KNO3)

32 grams of potassium nitrate (KNO3) water solubility at 20 degrees celsius (room temperature) can be dissolved in 100 milliliters (0.1 L) of water.

2 liters = 2000 milliliters

32 grams / 100 milliliters = x grams / 2000 milliliters

cross-multiply

100 * x = 32 * 2000

x = (32 * 2000) / 100

x ≈ 640 grams
