Ineed getting an idea for my science fair idea but my teacher said it had to be something useful and that you can research on. no silly experiments that last a day, !

How many moles are equivalent to 55.5g of nano3

Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.

What element has similar physical and chemical properties as boron.
