Calculate %tage by mass of all component element NaNo3 given,(Na=23,N=14,o=16)
I need the calculations
%Na = (mass Na/molar mass NaNO3)x 100
%N = (mass N/molar mass NaNO3) x 100
Etc.

To calculate the percentage by mass of each component element in NaNO3, we need to determine the molar mass of NaNO3 first. The molar mass is the sum of the atomic masses of all the atoms in the compound.
Molar mass of NaNO3 = (Atomic mass of Na) + (Atomic mass of N) + (3 x Atomic mass of O)
Given that Na has an atomic mass of 23, N has an atomic mass of 14, and O has an atomic mass of 16, we can calculate the molar mass of NaNO3 as follows:
Molar mass of NaNO3 = (23) + (14) + (3 x 16)
= 23 + 14 + 48
= 85 g/mol
Now, to find the percentage by mass of each element, we divide the molar mass of each element by the molar mass of the entire compound and multiply by 100.
Percentage of Na = (Molar mass of Na / Molar mass of NaNO3) x 100
= (23 / 85) x 100
≈ 27.06%
Percentage of N = (Molar mass of N / Molar mass of NaNO3) x 100
= (14 / 85) x 100
≈ 16.47%
Percentage of O = [(Molar mass of O x Number of O atoms) / Molar mass of NaNO3] x 100
= [(16 x 3) / 85] x 100
≈ 56.47%
So, the percentage by mass of each component element in NaNO3 is approximately: Na = 27.06%, N = 16.47%, and O = 56.47%.
