Answer:
there are 14 milligrams in 7 mL.
Explanation:
to find the number of milligrams in 7 mL, you can use the proportion:
(5 mg) / (2.5 mL) = (x mg) / (7 mL)
Where x is the number of milligrams in 7 mL. To solve for x, you can cross-multiply and divide:
(5 mg) * (7 mL) = (2.5 mL) * (x mg)
x = (5 mg) * (7 mL) / (2.5 mL)
x = 14 mg
