The mass of one mole of Neon is equal to the molar mass depicted on the periodic table. This is <span>20.1797 g.</span>
1 mole of h3bo3...........6.023*10²³ each h and B and 0 so we will have 3hydrogen+ 1 B+3 oxygen = 7*6.023*10²³ atoms
1 mole .......7*6.023*10²³atoms
4 moles ........x atoms
x=4*7*6.023*10²³.
The answer is cadmium its got 48 electrons which is y its number 48 on the period table
