The correct answer is 500mg.

First convert the ratio strength to a percentage(0.2%).

Drug X accounts for 0.0396 g of NaCl.

It would require 0.54 g of NaCl if that was all we were using.

Lastly, 0.54 g - 0.0396 = ~ 0.5 g NaCl ( or 500 mg, rounded as per the instructions ).

Why will one's feet drop if the head is lifted in a back float position in swimming?
harkovskaia [24]
That is because there must be perfect equalibrium between the body. It's like the fosbury flop, which was a why of high jumping that would allow high jumpers to "cheat" physics and leave equalibrium for short periods of time. If something goes up, something else must go down, this is a general rule becuase if it isn't true you would start floating out of the water
