The saturation level is only nominally dependent on the temperature of the water. At 20 °C one liter of water can dissolve about 357 grams of salt, a concentration of 26.3% w/w. At boiling (100 °C) the amount that can be dissolved in one liter of water increases to about 391 grams, a concentration of 28.1% w/w.
<h3>How do you calculate the solubility of salt in water?</h3>
Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
<h3>How do you calculate the concentration of salt in water?</h3>
Salt is the solute (the dissolving substance), and water is the solvent (the substance that dissolves another to create a solution). To make a salt solution by weight percent (w/v), you apply the formula w/v = (mass of solute ÷ volume of solution) × 100.

Answer:
scientists are uncertain of how long the resources will last.
Explanation:
It is hard to estimate how long certain natural resources will last because they are dependent upon the rate of consumption and other factors. There are many fields of studies going into alternative energy. Since the technology needed for some of these ideas will take time to be developed, alternative sources of energy must be found before the resources we already have run out.
Answer: An imbalance of electric charge I the surface of an object
-electric charges that are stationary or at rest
-charges that build up on an object
i think its CaNO4 but im not sure
