six. you add the number of atoms for both of the elements ei: H2O has to 3 atoms because 2+1 =3
Answer:
ε = 201.5
Explanation:
Given data-
mass of benzene = 25.8 mg
= 25.8×10^-3 kg
Atomic mass of benzene= 78.11 amu
volume of hexane = 250.00 ml = 0.2500 L
Absorbance = 0.266
Length of the cell = 1.00 cm
Hence concentration =
solving we get
= 0.00132 M
Formula:
A= εcl
A= absorbance
c= concentration and l= length of cell
now substituting values in the above formula
0.266= ε×0.00132×1.000
⇒ε =
⇒ε = 201.5
Answer:
i believe u mean "ionically". Yes it is.
Explanation:
The first one you did wrong on the side its GG not GgThe second one is wrong to on the side it its Tt not TTthe third one is wrong to on the side its tt, not TTthe last one is wrong to is wrong to the top is RR and the side is rr P.S i did this 1 year ago :PPPPthat the one i did to and the other one too *sigh*
