Asalt solution has a concentration of 200 g/l. how many grams of salt are contained in 500 ml of this solution?

100g/500mL

Explanation:

1ml is .001 of 1 L

this means that per one ml, there is 200g*.001, or .2g/mL, or simply .2g.

now we multiply this by 500, for the 500ml we are calculating. 500*.2=100.

We can also skip these steps and take 200g*.5L, as 500mL is 1/2 liter. We get the same outcome, so the answer is 100g
