Answer to Question #195033 in Chemistry for boo

Question

How many grams of sodium will result from the decomposition of 1.0 mole of sodium azide

Answer 1

Solution:

sodium azide = NaN₃

Balanced chemical equation:

2NaN₃(s) → 2Na(s) + 3N₂(g)

According to the equation above: n(NaN₃) = n(Na)

n(Na) = n(NaN₃) = 1.0 mol

The molar mass of Na is 23 g/mol

Hence,

(1.0 mol Na) × (23 g Na / 1 mol Na) = 23 g Na

Answer: 23 grams of sodium (Na) will result.
