You wish to prepare 0.13 M HNO3 from a stock solution of nitric acid that is 16.6 M. How many milliliters of the stock solution do you require to make up 1.00 L of 0.13 M HNO3?

Answer:

0.0078 L of the stock solution is required to make up 1.00 L of 0.13 M
HNO_(3)

Step-by-step explanation:

According to laws of equivalence,
C_(1)V_(1)=C_(2)V_(2)

where,
C_(1) and
C_(2) are initial and final concentration respectively.
V_(1) and
V_(2) are initial and final volume respectively.

Here,
C_(1)=16.6M,
C_(2)=0.13M and
V_(2)=1.00L

So,
V_(1)=(C_(2)V_(2))/(C_(1))

or,
V_(1)=((0.13M)* (1.00L))/((16.6M))

or,
V_(1)=0.0078L

Hence 0.0078 L of the stock solution is required to make up 1.00 L of 0.13 M
HNO_(3)
