C) They have a large number of rods and small number of cones.
Fluorine in compounds is always assigned an oxidation number of -1
Answer:
606 atoms
Explanation:
Add the numbers 145 + 293 + 168
Average atomic mass is the weighted average atomic masses with regard to the relative abundance of the isotopes
average atomic mass of Li = relative abundance of Li-6 x mass of Li-6 + relative abundance of Li-7 x mass of Li-7
average atomic mass of Li = (7.42% x 6.0151 a.m.u) + (92.58% x 7.0160 a.m.u)
= 0.446 + 6.495
= 6.941 amu
average atomic mass of Li is 6.941 amu
