Help! Please very much appreciated

Find the number of grams of hcl needed to react completely with .50 moles of magnesium.

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.

Find the mass, in grams, of 5.00*10^23 molecules of f2
