Given
15.0 wt% methanol
The flow rate of the methyl acetate :100 lbm/h
Required
the mixture flow rate in lbm/h
Solution
mass of methanol(CH₃OH, Mw= 32 kg/kmol) in mixture :
![\tt 15\%\times 200~kg=30~kg\\\\mol=\dfrac{mass}{MW}=\dfrac{30~kg}{32~kg/kmol}=0.9375~kmol](https://tex.z-dn.net/?f=%5Ctt%2015%5C%25%5Ctimes%20200~kg%3D30~kg%5C%5C%5C%5Cmol%3D%5Cdfrac%7Bmass%7D%7BMW%7D%3D%5Cdfrac%7B30~kg%7D%7B32~kg%2Fkmol%7D%3D0.9375~kmol)
mass of the methyl acetate(C₃H₆O₂,MW=74 kg/kmol,85% wt) in 200 kg :
![\tt 85\%\times 200=170~kg\\\\mol=\dfrac{170}{74}=2.297~kmol](https://tex.z-dn.net/?f=%5Ctt%2085%5C%25%5Ctimes%20200%3D170~kg%5C%5C%5C%5Cmol%3D%5Cdfrac%7B170%7D%7B74%7D%3D2.297~kmol)
Flow rate of the methyl acetate in the mixture is to be 100 lbm/h.
1 kg mixture = 0.85 .methyl acetate
So flow rate for mixture :
![\tt \dfrac{1~kg~mixture}{0.85~methyl~acetat}\times 100~lbm/h=117.65~lbm/h](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B1~kg~mixture%7D%7B0.85~methyl~acetat%7D%5Ctimes%20100~lbm%2Fh%3D117.65~lbm%2Fh)
Ionic is the answer. This is because lithium has a positive charge, while chlorine has a negative charge, meaning the compound doesn’t necessarily have an overall charge.
V1M1 = V2M2
<span>V1 × 2.5 = 1 × 0.75,
so V1 = 0.75/2.5
= 0.3 </span>
