The salinity of ocean water is measured in parts per thousand. Therefore, if the salinity of 500g of saltwater is 30ppt, there are 15g of dissolved salts in the seawater (1/2 of 30ppt = 15g). If the average salinity of seawater is 35ppt, how many grams of dissolved salts will 500g of seawater contain?
x/500 = 35/1000
To find out how many grams of dissolved salts will 500g of seawater contain, you can use the given average salinity.
If the average salinity of seawater is 35ppt, it means that for every 1000g (1kg) of seawater, there are 35g of dissolved salts.
To determine the amount of dissolved salts in 500g of seawater, you can set up a proportion:
35g/1000g = x/500g
To solve for x, cross-multiply and divide:
1000g * x = 35g * 500g
1000x = 17,500g
x = 17,500g / 1000
x = 17.5g
Therefore, 500g of seawater with an average salinity of 35ppt will contain 17.5g of dissolved salts.
To find out how many grams of dissolved salts there will be in 500g of seawater with an average salinity of 35ppt, we can use a proportion based on the given information:
Let's set up the proportion:
30ppt (15g) = 35ppt (x g)
To solve this proportion, we can use cross-multiplication. So we have:
30ppt × x g = 35ppt × 15g
Now we can calculate the value of x:
30x = 525
Divide both sides of the equation by 30:
x = 525 / 30
Simplify:
x = 17.5
Therefore, there will be 17.5 grams of dissolved salts in 500g of seawater with an average salinity of 35ppt.
