Question

How many milliequivalents of sodium chloride are in 4.5 mL of a solution that contains 4mEq/mL?

Answer 1

18mEq

Step-by-step explanation:

4/1 is the 4mEq/mL (mEq on top, mL on bottom) Then we'll cross mulitply with an equivalent fraction with mEq (unknown, "x") on top, 4.5mL on bottom

4/1 = x/4.5

x = 18mEq
