Homework Statement
Let u= i-3j+2k, v=i+j, and w=2i+2j-4k. Find.
(d)||3u-5v+w||
(e)(1/||w||)*w
(f)||(1/||w||)*w||
Homework Equations
||V||=sqrt(v1^2+v2^2+v3^2)
The Attempt at a Solution
ok so for d i did 3(sqrt(1^2-3^2+2^2))-5sqrt(1^2+1^2)+sqrt(2^2+2^2-4^2)
and got 3sqrt(14)...
Homework Statement
ok, so i had to do this determining molar mass by freezing point depression lab where we had to find the molar mass of an unknown solvent and then try to figure out the identity of the unknown solvent. i calculated my experimental molar mass to be 505.33 g/mol. does...
Im doing my chemistry lab and ran into trouble with this problem. I am not even where to start or what formulas to use. Any ideas? Thanks.
Suppose that a student calculated Kf of biphenyl to be 81.2 C kg/mol. Calculate the molar mass of an unknown if a solution containing 1.64g of an...

Hi, i have 2 questions about my chemistry homework i can not figure out
The first question is:
1)Silver ions can be precipitated from an aqueous solutions by the addition of aqueous chloride:
Ag+(aq) + Cl-(aq) ---->AgCl(s)
Silver chloride is virtualy insoluble in water so...
