C. 0.5
This is the answer.
(assuming that the D option is 1, if it is 0.1 then the answer is 0.1)
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.

Combine the two solutions. If the resulting salt is basic, you know the base was stronger. If you end up with an acidic salt, the acid was stronger.
Answer:
It lets people prepare for future weather hazards:
- If, in certain months and on certain dates, the past data shows that there's a history of rain or heat stroke on those days, people can prepare in the future for those events.
- They can also expect wind speeds, temperatures and stuff like that!
