The theoretical mass of sodium produced from two moles of NaN₃ is ________.

Question

Quizplus · Accepted Answer

The molar mass of NaN₃ is: (1 x atomic mass of Na) + (1 x atomic mass of S) + (1 x atomic mass of B) + (13 x atomic mass of U) = 22.99 + 32.06 + 10.81 + (13 x 238.03) = 3168.62 g/mol Two moles of NaN₃ would have a mass of: 2 mol x 3168.62 g/mol = 6337.24 g Theoretical mass of sodium produced would be half of the molar mass of NaN₃ (since the ratio of Na to NaN₃ is 1:1), which is: 3168.62 g/mol ÷ 2 = 1584.31 g/mol Therefore, the theoretical mass of sodium produced from two moles of NaN₃ is: 2 mol x 1584.31 g/mol = 3168.62 g, which is approximately 46 g.
