Answer:
Vapor pressure for solution is 22.4 Torr
Explanation:
P° → Vapor pressure of pure solvent
P' → Vapor pressure of solution
Formula for lowering vapor pressure is: P° - P' = P° . Xm
Xm is the mole fraction. Let's determine it:
0.220 mol of solute + 3.70 mol of water = 3.92 total moles
Mole fraction for solute → 0.220 / 3.92 = 0.056
23.8 Torr - P' = 23.8 Torr . 0.056
P' = - ( 23.8 Torr . 0.056 - 23.8 Torr ) → 22.4 Torr
Only C is correct.
A will produce either an methylbromide + alcohol
B will produce alcohol and alkyl bromide as well
C cyclic ether when reacted with HBr will only produce 1 product which has alcohol group (-OH group) on one end and Bromide group on the other end
Answer:
1.03M
Explanation:
mass/molar mass = moles of solution
50 g / (80+1) = 0.617 mol HBr
molarity*volume = moles
M*0.600 L = 0.617 mol
M = 0.617/0.600 = 1.03 M
Answer:
trees collect energy from sitting in the sun, the interact with their enviorment because they provide oxygen, and they reproduce when their fruit flowers or leaves fall off.
