Question

How many moles of sodium hydorixde are there in 1.0mL of 2.0M NaOH?

Answer 1

I can't make any definite promise that this is right but I think I might can help you with this problem. Give me just a second.

Answer 2

Okay

Answer 3

Ok I know that M or Molarity = moles/ L so you need to convert mL to L. I don't know how to type with dimensional analysis, but if you know how to do that it makes conversions easier. There is 1000 mL in 1 L. So using dimensional analysis you should put the calculate 1*1 = 1/ 1000 = .001 L. So now that you have converted to liters you just plug and chug. You should get .2M = .001L(x). Now you just solve the algebra. Divide both sides by .001 to solve for x. x=200 moles. I am pretty sure that is correct. If not I will look at it again, and actually use scrap paper to figure it.

Answer 28

I guess Mexico. Leo has lived here his entire life so I'm not exactly sure. I'm trying to surprise him by being able to have some kind of conversation with his parents. He doesn't even know that I know that his parents almost only speak Spanish, so I want it to be a good surprise that I tried to learn for when I met them. I think its the right thing to do to try to take the time to be able to have a basic conversation with them the first time I meet them and then learn from them as we go.

Answer 29

oh ok so you tell me the conversation you want and I'll translate well then you study
