this element is the only element that is shiny, mallable, and a good conductor of heat and electricity. it has a higher number a
Ainat [17]
I do not have my reference table out to see the periodic table but in order to achieve the answer pull out the periodic table. You now know that this element is going to be a metal because it is a good conductor of electric and is malleable. Next you will find both cesium and radon and look in between them to see which one is a metal that has an atomic number that lies between both radon and cesium

Using a spectrophotometer, and a cuvette with a path length of 1 cm you measure the absorbance (A275) of Guanosine to be 0.70. C
Anton [14]

Answer : The concentration of guanosine in your sample is, 8.33\times 10^{-5}M

Explanation :

Using Beer-Lambert's law :

A=\epsilon \times C\times l

where,

A = absorbance of solution  = 0.70

C = concentration of solution = ?

l = path length = 1.00 cm

\epsilon = molar absorptivity coefficient guanosine  = 8400M^{-1}cm^{-1}

Now put all the given values in the above formula, we get:

0.70=8400M^{-1}cm^{-1}\times C\times 1.00cm

C=8.33\times 10^{-5}M

Thus, the concentration of guanosine in your sample is, 8.33\times 10^{-5}M
