One (1) kilogram of seawater (35‰) contains __ grams of dissolved salts and grams of water?
Seawater is about 3.5 not 35 percent salt
.035 * 1000 = 35 grams salt
and
1000 - 35 grams H2O
To calculate the grams of dissolved salts and grams of water, we need to determine the composition of seawater in terms of salinity.
Step 1: Salinity is expressed as parts per thousand (‰), which represents the grams of dissolved salts per kilogram of seawater.
Given that the salinity is 35‰ and the total weight of seawater is 1 kilogram, we can calculate the grams of dissolved salts.
Grams of dissolved salts = Salinity (in ‰) x Total weight of seawater (in kilograms)
= 35‰ x 1 kilogram
= 35 grams
Therefore, there are 35 grams of dissolved salts in one kilogram of seawater.
Step 2: To find the grams of water, subtract the grams of dissolved salts from the total weight of seawater.
Grams of water = Total weight of seawater - Grams of dissolved salts
= 1 kilogram - 35 grams
= 965 grams
Therefore, there are 35 grams of dissolved salts and 965 grams of water in one kilogram of seawater.
To solve this problem, we need to know the concentration of the seawater, which is given as 35‰. This means that there are 35 grams of dissolved salts per 1,000 grams of seawater.
To find out how many grams of dissolved salts are present in 1 kilogram of seawater, we can set up a proportion:
35 grams of dissolved salts / 1,000 grams of seawater = x grams of dissolved salts / 1,000 grams of seawater
To solve for x, we can cross-multiply and divide:
x grams of dissolved salts = (35 grams of dissolved salts * 1 kilogram of seawater) / 1,000 grams of seawater
x grams of dissolved salts = 35/1 * 1/1 = 35/1 = 35 grams
Therefore, 1 kilogram of seawater (35‰) contains 35 grams of dissolved salts.
To find out how many grams of water are present in 1 kilogram of seawater, we can subtract the weight of the dissolved salts from the total weight of the seawater.
Weight of water = Total weight of seawater - Weight of dissolved salts
Weight of water = 1 kilogram - 35 grams = 1,000 grams - 35 grams = 965 grams
Therefore, 1 kilogram of seawater (35‰) contains 35 grams of dissolved salts and 965 grams of water.
