Answer:
The molar mass of N5O9
is 214.0245g/mol
Explanation:
To solve this problem, we need to know each number of mole of each element present in the compound
N has 5 moles
O has 9 moles
Then, we multiple each number of mole by its number of mass of each element present
N - 14.0067
O - 15.999
Multiplying by mole
N - 5 * 14.0067 = 70.0335
O - 9 * 15.999 = 143.991
Therefore,
Molar mass of N5O9 = 70.0335 + 143.991
= 214.0245g/mol

Answer:
<em>Nitrogen = 17.07%</em>
Explanation:
We are asked to calculate the percentage by mass of nitrogen in Ca(NO3)2.
The molar mass of calcium nitrate is 164,088 g/mol.
In this 164.088 g/mol there are 2 nitrogen atoms.
Molar mass of nitrogen = 14,0067 g/mol
% Nitrogen = molar mass of N/total molar mass of the compound
% Nitrogen =[(2 x 14.0067)/164.088]*100
% Nitrogen = 17.07%
