<PRE><B>Question 643799</B>
You received an order to prepare 500 ml of a 0.6% KCL solution. Your pharmacy only has a 10% KCL solution in stock. How many milliliters of the stock KCL solution would prepare this solution? How much distilled water do you need to add to produce the final product?
------------------------------------------------
Equation:
water + water = water
0.90x + x = 0.994*500
1.9x = 497
x = 261.58 (amt. of distilled water needed)
0.9x = 235.42 (amt of 0.6% KCL solution needed)
=================================================
