ComPLETE THE FOLLOWING EQUALITIES

1molBa(OH)2FU=____g Ba(OH)2=____Ba(OH)2FU

1Na atom=______amu Na

i don't understand how to do this ????

  • chemistry please help me -

    If FU stands for formula unit, then take the atomic masses from the periodic table and add them.
    Ba = 137. something
    2*Oxygen = 2*16 = 32
    2*hydrogen = 2*1= 2
    Then add 137.something + 32 + 2 = ?

    For the second one, 1 atom is the atomic mass found on the periodic table in amu. So 22.998 amu is the mass of 1 Na atom.
