1 Answer
Answer:
Explanation:
This is a dilution chemistry problem. For problems like this one, use the following equation
Where
Whenever you dilute a concentrated stock solution, or for that matter, any solution, you are essentially changing the volume of that solution by adding water. If we look at what
you can see when you increase the
Using our equation from above, we can find the number of moles of nitric acid,
We will let

#M_1V_1 = M_2V_2# 
#(0.125L)(8.0M) = (12.0M)(V_2)# 
#((0.125L)(8.0cancelM))/(12.0cancelM) = V_2# 
#"0.083 L"= V_2#
Answer: 0.083 L
