The molar absorptivity is
Molar absorptivity is defined as the measure a compound's ability to absorb light of a specific wavelength. It is represented by the constant/symbol 'ε'.
The molar absorptivity is given by :
A = εcl
where A is the absorbance
ε is the molar absorptivity
c is the molar concentration of the compound
and l is the path length
here, the molar concentration of the solution is 0.16 mol
and the path length is 1 cm
to find the molar absorptivity , one must know the absorbance of the material.

No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol
Mr of Na2O = 23+23+16 = 62 g/mol
n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol
m = n x Mr
m = 0.0652 mol x 62 g/mol
m = 4.04 g
Answer:
C.it contradicted the heinsberg uncertainly principle
6.270/56.11 = 0.1117447870 /0.1117.. ≈ 1
19.67/44.01 = 0.446943876 /0.1117.. ≈ 4
8.055/18 = 0.4475 /0.1117.. ≈ 41 mole of compound forms 4 moles of both CO2 and H2O, so the empirical formula will be C4H8
As this gives molar mass of 56.11, this is also the molecular formula
This could be cyclobutane, or butene
