Answer:
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
