For the imaginary element abdicinium (Ab), two isotopes exist. Isotope one has a mass of 40.005 amu with a relative abundance of 14.00%. Isotope two has a mass of 41.008 amu with a relative abundance of 86.00%. What is the atomic mass of the element

The average atomic mass of abdicinium is 40.8676 amu

Explanation:

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

  .....(1)

Mass of isotope 1 = 40.005 amu

Percentage abundance of isotope 1 = 14.00 %

Fractional abundance of isotope 1 = 0.1400

Mass of isotope 2 = 41.008 amu

Percentage abundance of isotope 2 = 86.00 %

Fractional abundance of isotope 2 = 0.8600

Putting values in equation 1, we get:

Hence, the average atomic mass of abdicinium is 40.8676 amu

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

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.
