Answer 1

So how far can you get on your own? Show me your best try so I can help you figure it out.

Answer 2

I think I've figured out what to do, but I'm not completely sure.
Give me just a moment, and I'll show you.

Answer 3

I'm not exactly good at explaining how to solve things, so bear with me.
I got 200 mL.

Answer 4

That's ok so far so good. =)

Answer 5

First I converted 50 mL of H2SO4 to 0.05 L.
Then I multiplied the 0.05 L by the 2.00 M and got 0.10 moles of H2SO4.
Using the 2:1 ratio of NaOH:H2SO4, I multiplied 0.10 by two and got 0.20 moles of NaOH.
I then divided the 0.20 moles by the 1.00 M of NaOH to get the needed Liters and coverted 0.20 Liters to 200 mL.
I apologize if this doesn't make any sense.

Answer 6

That actually sounds perfect, it sounds like you know exactly what you're doing and made perfect sense haha. In fact that's probably one of the clearest explanations I've ever read. I checked the math and it appears to be perfect as well, good job.

Answer 7

Wow, really? Thank you for the compliment and clarification. :)

Answer 8

Yeah, I was actually hoping I could still help you some how though. When you're doing this, how do you keep all of your conversions straight, for instance how did you know that you needed to divide "0.20 moles by the 1.00 M of NaOH to get the needed Liter"?

Answer 9

My teacher gave us a few equations to help us remember how solve for moles, molarity, and volume.

Answer 10

\[Molarity = \frac{ Moles }{ Liters }\]
\[Molarity(Liters) = Moles\]
\[Liters = \frac{ Moles }{ Molarity }\]
