How many moles of iodomethane are in 1.00g?(show working for all calculations)?
Answers:
Do your own feckin' homework, Junior.
There are 0.007 moles of iodomethane in 1.00g. You take 1.00g and divide by the molar mass of iodomethane, which I calculated to be 141.9g. The grams cancel out and you are left with your answer in moles of iodomethane.
1.00g x 1mole/141.9g = 0.007 moles iodomethane
Hope this helps, I have my chem class in a few hours.good practice for me, thanks.
Iodomethane's chemical formula is CH3I.
It is asking you how many mols are in 1.00 g of CH3I. So we should find the molar mass of CH3I.
C -> 1 x 12.0 = 12.0
H -> 3 x 1.01 = 3.03
I -> 1 x 126.9 = 126.9
TOTAL = 141.93 g
Now we can find how many mols are in 1.00 g of CH3I.
1.00 g of CH3I = 1 mol/141.93 g = 0.007 mols of CH3I
The two g symbols cancel out. To determine this answer, divide 1.00 by 141.93 (the molar mass).
