The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
you could use any of these.
Answer
The mole ratio is 1:1
The molar mass of potassium hydrogen phthalate (C8H5KO4) is 204.22g/mol
The mass of C8H5KO4 is 0.43g
The no of moles of C8H5KO4 = mass/molar mass
No of Moles of C8H5KO4 = 0.000210557242mol
From Mole ratio the no of mole of NaOH that reacted with C8H5KO4 0.000210557242
Therefore, molaroty of NaOH is mole of NaOH/the Volume in L
Molaroty if NaOH = 0.000210557242/0.02411 = 0.08733M
Answer: The isotopic abundance of Cl- 37 is 0.2424.
Explanation:
Mass of isotope - 35 = 34.96885 amu
% abundance of isotope -35= x% =
Mass of isotope - 37 = 36.9659 amu.
% abundance of isotope-37 = (100-x)% =
Formula used for average atomic mass of an element :
Therefore, the isotopic abundance of Cl- 37 is 0.2424.
