What is the molar mass of LiNO₃?

Answer

M(LiNO₃) ≈

68.94 g/mol

Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — Li: 6.94.

Contribution of each element
Element	Atoms, n	Atomic weight, A	n × A, g/mol Mass fraction, w	Mass fraction, w
Lilithium	1	6.94	6.94 w ≈ 10.07%	≈ 10.07%
Nnitrogen	1	14.007	14.007 w ≈ 20.32%	≈ 20.32%
Ooxygen	3	15.999	47.997 w ≈ 69.62%	≈ 69.62%
Σ = 68.944 ≈ 68.94 g/mol w = 100%				100%

Each fraction is rounded on its own, so the printed ones add up to 100.01%; unrounded, they make exactly 100%.
