you are a dental assistant. you are preparing a disinfectant solution using 2.5 liters of water. the iodophor concentrate is added to the water at a rate of 4.5 cubic centimeters per liter. how many cubic centimeters of iodophor concentrate should you add to the water

Respuesta :

4.5 cc per 1 L
X cc per 2.5 L
Cross multiply:
1*x L-cc = 2.5*4.5=11.25 L-cc
x=11.25 L-cc / (1 L)
=11.25 cc    (after the units L have been cancelled)
