PLEASE HURRY TIME LIMIT WILL GIVE BRAINLIEST A solution is made using 80.1 g of toluene (MM = 92.13 g/mol) and 80.0 g of benzene
(MM = 78.11 g/mol). What is the molality of the toluene in the solution?
1 answer:
10.9 because of mass= moles/mv it’s just basic chemistry

Answer:
P₂ = 140 KPa
Explanation:
Given data:
Initial volume = 8.0 L
Final volume = 4.0 L
Initial pressure = 70 KPa
Final pressure = ?
Solution:
According to Boyle's law
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = 70 KPa ×8.0 L/4.0 L
P₂ = 560 KPa .L / 4.0 L
P₂ = 140 KPa
Answer choice would be D, answer choice B, is the boxes net force. Velocity = distance/time. The correct answer is D. I hope this helps!
I just looked it up and I found this:
Polar substances are likely to dissolve in polar solvents
Hope this helps!
Because as u go across groups the more reactive it is due to the ability of electrons to be given or taken away
