M. 1 V 1 = M 2 V 2 The "sub one" refers to the situation before dilution and the "sub two" refers to after dilution. This equation does not have an official name like Boyle's Law, so we will just call it the dilution equation. Example #1 - 53.4 mL of a 1.50 M solution of NaCl is on hand, but you need some 0.800 M solution. How many mL of 0.800 ...

3. To perform an experiment, you need 0.300 L of 6.0 M nitric acid. You go to the acid cabinet and discover that you have 100 mL of concentrate. Will you have enough acid to complete the experiment? Show your calculation and explain your answer. 4. You mix 128 mL of an unknown, concentrated acid with water and get 1.54 L of a 1.5 M acid solution.

Aug 23, 2002 · The quality of the dilution air must be judged to be odor free by all panel members and the panel moderator. Dilution Factor: A dimensionless factor based on the ratio of sample flow into the total flow. Sample calculation: dilution air flow rate, actual 4860 ml/min. sample flow rate, actual 286.4 ml/min. dilution factor = 4860 + 286.4 = 18.0
