thank you. i'm confused thought....i tried to use a formula that already had molality in it because i don't have a mass to use, hence the g/GMW kg portion. i need to use 175 mL and make it boil at 245 degrees F.

thank you so much! the molar mass was a major problem...i didn't realize i was so off. thank you for pointing that out.

oui, partager [the infinitive of partage] means share.

the atomic mass in the periodic table represents the number of grams per one mol of lead. so there are 207.1 g per mol of lead.

Oh okay so for this one would it be: 40 Ar 18???? thanks so much for your help!

yeah that's right, can u go on?

Thanks but I don't really get what your saying? Does that mean your saying government regulation helps keep things in order? Does that mean it's necessary though i really don't know? Do you have any links about this subject because I need to write about 1...

Oh Sorry I thought it was rhetorical, but I would have to say Yes to all of them, which I guess would mean it's necessary for government regulation for most businesses. Are there any cases where it's not necessary though?

Oh wow! I guess I never really noticed that. I can't put my finger on the tone of the piece though. I can't think of a word to really describe it.

Thank you so much! When I say tone, I'm referring to the feeling behind the passage.. Ex: Dr. Seuss writing has a light, whimsical tone. Or Joan Dilard tends to be very dark and brooding.

it isn't necessary to change the mass in grams to moles. the equation reads out q=s*m*(final temp - initial temp) where q is the change in enthalpy, s is specific heat, and m is mass.

oh okay-thank you

Thank you for doing that-I really appreciate it-I'm alittle confused on this stuff

consecutive integers are integers like 1,2,3 or 3,4,5 or 101,102,103. So since the largest of the integers is k, to get the consecutive integers lower than k, you have to find the second integer which would be k-1, then the third which would be k-2.
