Calculate the average atomic mass of argon to two decimal places, given the following relative atomic masses and abundances of each of the isotopes: argon-36 (35.97 u; 0.337%), argon-38 (37.96 u; 0.063%), and argon-40 (39.96 u; 99.600%)

39.95 u

Explanation:

The formula for the calculation of the average atomic mass is:

Given that:

For first isotope, Argon-36:

% = 0.337 %

Mass = 35.97 u

For second isotope, Argon-38:

% = 0.063 %

Mass = 37.96 u

For third isotope, Argon-40:

% = 99.600 %

Mass = 39.96 u

Thus,  

Average atomic mass = 39.95 u

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
