Lithium-6 has a mass of 6.0151 amu and lithium-7 has a mass of 7.0160 amu. the relative abundance of li-6 is 7.42% and the relative abundance of li-7 is 92.58%. based on this data alone, calculate the average atomic mass for lithium to the correct number of significant digits.

The average atomic mass of Lithium is 6.94 amu.

Explanation:

Mass of isotope Li-6 = 6.0151 amu

% abundance of isotope  Li-6 = 7.42%=

Mass of isotope Li-7=  7.0160

% abundance of isotope Li-7 = 92.58% =

Formula used for average atomic mass of an element :

Therefore, the average atomic mass of Lithium is 6.94 amu.

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.
