An iv order calls for the addition of 35 meq of calcium carbonate. you have a 50 ml vial of caco3 4.4 meq/ml. how many ml's of this concentrate do you need to add to this iv?

V = 7.95 mL

Explanation:

We have in the 50 mL vial the next quantity of CaCO₃:

Knowing that in 50 mL we have 220 mEq of CaCO₃, to have 35 mEq we need the following volume of the concentrate (Vc):

Therefore, for the addition of 35 mEq to the IV order, we need 7.95 mL of the concentrate 4.4 mEq/mL of CaCO₃.

I hope it helps you!      

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
