Hey guys!
What’s the Molecular mass for “3Ba(NO3)2”
Please help out thank u so much

261.34 is the mass

Explanation: Multiply the subscript (number of atoms) times the atomic mass of that element and add the masses of all of the elements.

261.34

Explanation:

i think it help

a graduated cylinder.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
