Solution
Well, how many barium nitrate formula units are in 261.35⋅g
Explanation:
It is fact that 6.023∗10
23
formula units of barium nitrate have a mass of 261.35⋅g. This is what we specify when we say molar mass. And thus the mass of 5.30∗10
22
formula units of barium nitrate is the quotient multiplied by the molar mass:
6.023∗10
23
5.03∗10
22
mol∗261.35⋅g⋅mol
−1
