Final answer:
5 grams of CaCl2 will dissolve to form a saturated solution in 10 mL of water.
Step-by-step explanation:
To determine the amount of CaCl2 that will dissolve in 10 mL of water, we can use the given solubility of CaCl2 in water. The solubility is given as 25 g per 50 mL of water. We can set up a proportion to find the amount of CaCl2 that will dissolve in 10 mL of water:
25 g / 50 mL = x g / 10 mL
Cross-multiplying and solving for x, we get:
x g = (25 g / 50 mL) * 10 mL
x g = 5 g
Therefore, 5 grams of CaCl2 will dissolve to form a saturated solution in 10 mL of water.
