What is the Percent of Salt by Weight in Mono Lake at Different Water Levels?

In summary, the task is to find the percentage of salt by weight for Mono Lake's water levels, with the given information that the lake is considered a salt lake if the concentration of salt is greater than 3% by weight. Using the given data of 6417 feet above sea level and 51.3 grams per liter of salt, the calculated percentage is 79%. However, it is important to note that this calculation does not take into account the effects of elevation and pressure on the lake's salt concentration.

Homework Statement



When the concentration of salt in a lake is greater than three percent by weight, the lake is a salt lake.

Find the percent of salt by weight for each of the water levels of Mono Lake Shown in the table. One liter of water weighs 1kg or 1000 grams.

Water level (Feet above sea level) 6417
Salt Content (grams per liter) 51.3


Homework Equations



Unknown

The Attempt at a Solution



6417+51.3 = 6468.3
51.3/6468.3 = 0.0079309
0.0079309 * 100 = 79%
Thanks

This is relatively simple. If there are 51.3 grams per litre of water, then how will you work out the percentage? What is the mass of 1 litre of water?

? Please check your math.

One should show units in the equations.

Why 6417+51.3 = 6468.3. 6417 feet + 51.3 g/l makes no sense.

The elevation would affect pressure at the surface of the water, but is that relevant?

Mono Lake - http://en.wikipedia.org/wiki/Mono_Lake
Average depth: 17 m (57 ft)
Max depth: 48 m (159 ft)


If one simply take 1 liter and assumes little change in volume with the 51.3 g of salt then,

1 liter has 1000 g of water and 51.3 g of salt, so . . . .

What is the volume of the salt?

Related to What is the Percent of Salt by Weight in Mono Lake at Different Water Levels?

1. What is the definition of "Percent of Salt by Weight"?

"Percent of Salt by Weight" refers to the amount of salt present in a substance, measured as a percentage of the total weight of the substance. It is commonly used in food and chemical industries to determine the concentration of salt in a solution or mixture.

2. How is "Percent of Salt by Weight" calculated?

"Percent of Salt by Weight" is calculated by dividing the weight of the salt present in a substance by the total weight of the substance, and then multiplying by 100 to get the percentage.

3. Why is "Percent of Salt by Weight" important?

"Percent of Salt by Weight" is important because it can affect the taste, texture, and overall quality of a product. In food products, the percentage of salt can impact the flavor profile, while in chemical substances, it can impact the effectiveness of the product.

4. How is "Percent of Salt by Weight" measured in a laboratory setting?

In a laboratory setting, "Percent of Salt by Weight" is typically measured using analytical techniques such as titration, gravimetric analysis, or spectrophotometry. These methods involve precise measurements and calculations to determine the percentage of salt present in a sample.

5. Can "Percent of Salt by Weight" be converted to other units of measurement?

Yes, "Percent of Salt by Weight" can be converted to other units of measurement such as grams per liter or milligrams per kilogram. These conversions can be useful when comparing salt concentration in different substances or when determining the appropriate amount of salt to add to a solution or mixture.
