For a barrel of 119 L, at 20 0C, the amount of salt will be 42 947 kg.
Knowing how to make a barrel .
When you add water to the saturated solution, there is more solvent to dissolve the solute. The saturated solution becomes diluted, so it is no longer saturated.
The solubility of cerium sulfate at 30°C is approximately 117 g/100 mL of water. To make a saturated solution, you would need to add at least 117 g of cerium sulfate to 100 mL of water at 30°C.
Knowing how to make a barrel .
You need min. 5,63 g cerium sulfate.
To make the barrel of water weigh 12 pounds, you would need to remove 8 pounds of water from the barrel.
Probably to cause the water it to be saturated without using as much salt as it would take to make room temperature water saturated.
To prepare a saturated solution of copper sulfate at 20 degrees Celsius, you would need to dissolve approximately 203 grams of copper sulfate in 400 grams of water. This is based on the solubility of copper sulfate in water at that temperature.
The solubility of cerium sulfate in water at 30 degrees Celsius is 114 g/L. To make a saturated solution in 100 ml of water, you would need to calculate the amount of cerium sulfate that can dissolve in that volume at that temperature. This would be approximately 11.4 grams of cerium sulfate.
all you have to do is add sugar into boiling water. the sugar will dissolve and make saturated sugar!!
To make a barrel planter, you will need a large barrel, drill drainage holes in the bottom, fill it with soil, and plant your desired plants. Make sure to water and care for the plants regularly.
It is impossible to make a saturated solution of ethanol or methanol and water because ethanol and methanol are completely miscible in all proportions. Some other alcohols may be less miscible and, if so, they could make a saturated solution. I will leave the question open with regards to ALL ALCOHOLS.
