What is the total mass of Chloroform in the second sample found?Answer
A sample of chloroform is found to contain 12.8 g of carbon, 113.5 g of chlorine, and 1.08 g of hydrogen. If a second sample of chloroform is found to contain 35.9 g of carbon, what is the total mass of chloroform in the second sample?
What do I do? =/
WIll give best answer!
I just had this same question! Is it for WebAssign?
ugh.. Never mind that LOW LIFE who answered first.. obviously his stupidity overrides his ability to do a basic Chem problem. ANYWAYS, its a cross- multiplication problem.. on one side you have the mass of C/total mass of the first sample of Chloroform. One the other side you have 35.90g C/ X (the total mass of the second sample of Chloroform)
12.8g/127.4g Chloroform = 35.9g/X
Then you cross multiply to solve..
127.4x35.9= 4,573.6/ 12.8 = 357.32 <---- that's your answer. But round to three sig fig's to have 357g
It's outside? Earlier, you said it was in your attic. You've asked various questions about this supposed Tokay gecko and are causing people to raise a few eyebrows. How about just leaving it alone? If it's been living in your attic for years like you claim (even though you just discovered it a few days ago when your internet went out), then it obviously isn't bothering anyone. And no, chloroform isn't a good idea.
What types of intermolecular interactions does chloroform exhibit?Answer
What types of intermolecular interactions
does chloroform (CH3Cl) exhibit?
I) London dispersion
III) hydrogen bonding
IV) covalent bonding
Recall that chloroform is tetrahedral
elctronic geometry with C as the central atom.
1. I, II, and III only
2. II and III only
3. I and II only
4. II and IV only
5. II only
I) All substances have dispersion forces so 1 must be true
II) Chloroform is a polar molecule so will have dipole-dipole interactions
III) Chloroform does not have H bonded to F, O, or N so cannot have H-bonding
IV) Chloroform does have covalent bonds, but covalent bonding is an intramolecular force not an intermolecular force
The correct answer is 3. I and II only
