Molar mass is 28+32 = 60
So take 3.4 x 10^-7/60 and get about 5.7 x 10^-9
<span>What is the relationship between the atomic numbers and ionic radii of the elements in group 1? What is the relationship between atomic numbers and first ionization energies?
</span>Answer:
When we see down the groups, the atomic number and the atomic radius both increase.Extra shells are produced which increase the size of the higher atoms.
If we go across the periods, the atomic radius decreases due to the higher nuclear charge in the atoms. This pulls the electrons more closer to the nucleus.
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
The closest to this definition would be the 2nd option.

Answer:
T = 401.356 K (128.356°C)
Explanation:
boiling point:
∴T: boiling temperature of the solution
∴ T*: boiling temperature of pure solvent = 118.5°C ≅ 391.5 K
∴ K: boiling point constant = 3.08 K.Kg/mol
∴ m: molality [=] mol/Kg = 3.20 m
∴ solvent: acetic acid
∴ solute: Ca(NO3)2
⇒ T = T* + (K)(m)
⇒ T = 391.5 K + ((3.08 K.Kg/mol)(3.20 mol/Kg))
⇒ T = 391.5 K + 9.856 K
⇒ T = 401.356 K
