Answer : The concentration of guanosine in your sample is, 
Explanation :
Using Beer-Lambert's law :

where,
A = absorbance of solution = 0.70
C = concentration of solution = ?
l = path length = 1.00 cm
= molar absorptivity coefficient guanosine = 
Now put all the given values in the above formula, we get:


Thus, the concentration of guanosine in your sample is, 

now split the equation in half
CH4+O2 I CO2 + 4H2O
C = 1 I C = 1
H = 4 I H = 8
O = 2 I O = 3
CH4+ 2O2 = CO2 + 2H20
Answer:
It has no fixed shape and therefore takes the shape of the part of the container in which it is placed
