A nurse practitioner prepares 470. mL of an IV of normal saline solution to be delivered at a rate of 85 mL/h. What is the infusion time, in hours, to deliver 470. mL?

Infusion time is 5.5 h

Explanation:   Time is   470 ml / 85 ml/h =  5.5 h

hope this !

explanation:

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
