Percent water in the hydrate can be calculated using the formula: % water = [(mass of hydrated salt - mass of anhydrous salt) / mass of hydrated salt] x 100 Substitute the given values to find the percent water in the hydrate.
To convert the solution from m percent salty to 2m percent salty, you need to add m/2 grams of salt. This will ensure that the ratio of salt to water in the solution is doubled, resulting in a 2m percent salty solution.
To make a 22.3% salt solution, you would dissolve 22.3 grams of salt in 100 grams of solution (salt + water). This would result in a solution where 22.3% of the total weight is salt.
Salt does not evaporate with water, so all the salt that was initially in the water remains behind once the water has evaporated. This is because salt has a much higher boiling point than water and remains in solid form when the water evaporates.
Salt water taffy does not contain actual seawater or salt water as an ingredient. The name "salt water taffy" likely originated from its coastal origins and traditional recipe that includes salt. However, the amount of salt water in salt water taffy is negligible.
75% of the water, I would assume.
About 97% of the Earth's water is salt water found in oceans and seas.
98 mL
we learned this in science. 70 to 75 percent of salt water covers the earth. hope this helped.
Approximately 97.5 percent of all the water on Earth is salt water. Of the remaining 2.5 percent that is fresh, about 70 percent exists as ice.
In the world,1% is fresh water,2% ice, and 97% salt water.
Approximately 67.8% of earth's surface is covered by salt water while only 3% is covered by fresh water. In total, the earth's surface is covered by 70.8% of water.
Dissolve 15 g salt in 100 mL water.
will the percent water loss be more or less if you heat the salt a little too much and it decomposed and vaporized
98 percent is salt water, so we can not drink that. So then you have 2 percent. But 1 percent of that is in glaciers. So we have access to about 1 percent.
About 70 percent of the Earth's surface is covered in water, and about 90 percent of that is salt water.
Sea water has arround 3.5 % of salt.
