Chapter 9: Q. 9.18 (page 294)

An intravenous solution to replace potassium loss contains $40 m E q / L$ each of $K^{+}$ and $C l^{-}$ . How many moles each of $K^{+}$ and $C l^{-}$ are in $1.5 L$ of the solution?

Short Answer

Expert verified

In $1.5 L$ of the solution, moles of $K^{+}$ and $C l^{-}$ are $0.06$ and $0.06$ respectively.

Step by step solution

Given Information.

Potassium loss contains $40 m E q / L$

Solution is $1.5 L$

To find the moles present in the solution.

Find the equivalent.

$1 L$ of intravenous solution contains $40 m E q / L$

Therefore, convert $m E q$ to $E q$ as follows:

$1 Eq = 1000 mEq = 40 m E q \times \frac{1 Eq}{1000 mEq} = 0.04 E q$

Find the moles in K+

Charge of Potassium is $+ 1$ . Therefore,

$1 E q o f K^{+} = 1 m o l e o f K^{+}$

$= 1.5 L \times \frac{0.04 Eq of K^{+}}{1 L} \times \frac{1 mol of K^{+}}{1 Eq of K^{+}} = 0.06 m o l e o f K^{+}$

Hence, mole of $K^{+}$ ions is $0.06 m o l e s$

Find the moles in Cl-

Charge of Chlorine is $- 1$ . Therefore,

$1 E q o f C l^{-} = 1 m o l e o f C l^{-}$

Then,

$= 1.5 L \times \frac{0.04 Eq of {Cl}^{-}}{1 L} \times \frac{1 mol of {Cl}^{-}}{1 Eq of {Cl}^{-}} = 0.06 m o l e s o f C l^{-}$
