This is a proportion problem. Call the unknown mass in grams of compound m. Then 4.50/18.3 = m/100; m =450/18.3 = 24.6 g, to the justified number of significant digits.
You can set up a proportion to find out. The amount of compound that will dissolve in 100 g of water can be calculated as (4.50 g / 18.3 g) * 100 g = 24.59 g. Therefore, approximately 24.59 grams of the compound will dissolve in 100 g of water.

Approximately 161 grams of lead nitrate will dissolve in 100mL of cold water at room temperature.
Because water is a polar compound and a universal solvent and it can easily dissolve many things in it while oil is a non-polar compound and it cannot dissolve things in it much fastly.
Water disrupts many ionic bonds, causing the ionic compound to dissolve in the water.
The amount of salt that can dissolve in 20mL of water depends on the solubility of the salt at that temperature. For common table salt (sodium chloride), approximately 36 grams can dissolve in 20mL of water at room temperature.

The solubility of RaSO4 in water is very low, approximately 0.036 g per 100 mL of water at room temperature. Therefore, only a very small amount of RaSO4 (about 0.036 g) would dissolve in 100 mL of cold water.
100 g water dissolve 45,8 g potassium chloride at 50 o 0C.
Suppose you get enough water to dissolve 10 grams in 15 minutes (I assume you're talking about dissolving in water). Then you can dissolve another 10 grams by fetching an equal volume of water and doing the same, also in 15 minutes. Keep doing this. You'll never run out of water. So I suppose the answer is "as many grams of salt as you can find". Or, reading the question differently, the answer could be "as many grams of salt you can find in 15 minutes."
Yes, H₂O (water) is a pure compound because it contains only two types of atoms (hydrogen and oxygen) chemically bonded in a fixed ratio. It is a substance with a definite composition and distinct chemical properties.
