Using data from the table below, calculate the freezing and boiling points of 2.04 g KBr and 4.82 g glucose (C6H12O6) in 188 g H2O. Given: Kb of H2O: 0.51 C/m; Kf of H2O: 1.86 C/m.I'm not really looking for the answer (though I won't complain if you provide it), I'm just confused as to what I need to do if I have a solution with two solutes.I know I need to use the equation Delta(Tb)=Kb*m*i and Delta(Tf)=Kf*m*i.I know how to figure it out if it's only 1 solute but I'm confused as to what to do if I have two solutes.(By the way, I put this under my course ENGR 202; it's actually for ENGR 106 but it wasn't wanting to load that course. Anyways, that's trivial.

In an experiment, 700 mL of 0.5 M hydrochloric acid (HCl) is added to 600 mL of 0.5 M sodium hydroxide (NaOH) solution. The acid and base neutralize each other according to the equation: HCl + NaOH ---> NaCl + H2O

How many moles of acid and base were there originally?

The answer is 0.35 mole of HCl and 0.3 mole of NaOH

but, I can't seem to get that answer when I calculate it, so I'm not sure where I am going wrong.

Update: I figured it out.

.5 M x .7L = .35 mole of HCl

.5 M x .6L = .3 mole of NaOH

I am given the two equations:
Cl2(g)+F2(g) 2ClF(g)
ClF(g)+F2(g) ClF3(g)

Question:
a) Write overall equation
b) Show that the overall Kc equals the product oftheKc's for the individual steps

Results:
a) Cl2(g)+3F2(g) 2ClF3(g)

- My professor gave me this answer but he showed no steps onhow toget to that. When i tried to solve it i was cancelingtheF2's out. This does not seem to be the way to solveit.Could you explain how he got that?

b)K1=[ClF]2/[Cl2][F2]
K2=[ClF3]/[ClF][F2]
KT=K1x K2=[ClF3]/[Cl2][F2]3

- I did not know how to get the overall equation from question asothis might be why i do not understand this result. Couldyouexplain in steps why this is?
