Answer 1

Answer:

.14L or 140mL

Explanation:

This is a classic plug-n-chug problem. Your textbook probably goes over this formula as $M_{1}V_{1} = M_{2}V_{2}$. M stands for molarity of the given substance, and V stands for the volume that the substance occupies.

Simply plug in the values that you're given, like so:

$M_{1} = 1.5M\\V_{1} = ???\\M_2 = 7M\\V_2 = .03L$

$1.5M * x = 7M * .03L$

After completing the algebra portion and solving for the unknown, you will be left with x = .14L, which is the volume required to neutralize 30mL of 7M NaOH.
