Question

How many moles of sodium can be produced if 378.3 grams of sodium azide is used

Answer 1

5.82 moles of sodium will produced.

Step-by-step explanation:

Given data:

Mass of sodium azide = 378.3 g

Moles of sodium produced = ?

Solution:

Chemical equation:

2NaN₃ → 2Na + 3N₂

Moles of sodium azide:

Number of moles = mass/ molar mass

Number of moles = 378.3 g/ 65 g/mol

Number of moles = 5.82 mol

Now we will compare the moles of sodium azide and sodium.

NaN₃ : Na

2 : 2

5.82 : 5.82
